+Section 2 -- Scope.
+
+  a. License grant.
+
+       1. Subject to the terms and conditions of this Public License,
+          the Licensor hereby grants You a worldwide, royalty-free,
+          non-sublicensable, non-exclusive, irrevocable license to
+          exercise the Licensed Rights in the Licensed Material to:
+
+            a. reproduce and Share the Licensed Material, in whole or
+               in part; and
+
+            b. produce, reproduce, and Share Adapted Material.
+
+       2. Exceptions and Limitations. For the avoidance of doubt, where
+          Exceptions and Limitations apply to Your use, this Public
+          License does not apply, and You do not need to comply with
+          its terms and conditions.
+
+       3. Term. The term of this Public License is specified in Section
+          6(a).
+
+       4. Media and formats; technical modifications allowed. The
+          Licensor authorizes You to exercise the Licensed Rights in
+          all media and formats whether now known or hereafter created,
+          and to make technical modifications necessary to do so. The
+          Licensor waives and/or agrees not to assert any right or
+          authority to forbid You from making technical modifications
+          necessary to exercise the Licensed Rights, including
+          technical modifications necessary to circumvent Effective
+          Technological Measures. For purposes of this Public License,
+          simply making modifications authorized by this Section 2(a)
+          (4) never produces Adapted Material.
+
+       5. Downstream recipients.
+
+            a. Offer from the Licensor -- Licensed Material. Every
+               recipient of the Licensed Material automatically
+               receives an offer from the Licensor to exercise the
+               Licensed Rights under the terms and conditions of this
+               Public License.
+
+            b. Additional offer from the Licensor -- Adapted Material.
+               Every recipient of Adapted Material from You
+               automatically receives an offer from the Licensor to
+               exercise the Licensed Rights in the Adapted Material
+               under the conditions of the Adapter's License You apply.
+
+            c. No downstream restrictions. You may not offer or impose
+               any additional or different terms or conditions on, or
+               apply any Effective Technological Measures to, the
+               Licensed Material if doing so restricts exercise of the
+               Licensed Rights by any recipient of the Licensed
+               Material.
+
+       6. No endorsement. Nothing in this Public License constitutes or
+          may be construed as permission to assert or imply that You
+          are, or that Your use of the Licensed Material is, connected
+          with, or sponsored, endorsed, or granted official status by,
+          the Licensor or others designated to receive attribution as
+          provided in Section 3(a)(1)(A)(i).
+
+  b. Other rights.
+
+       1. Moral rights, such as the right of integrity, are not
+          licensed under this Public License, nor are publicity,
+          privacy, and/or other similar personality rights; however, to
+          the extent possible, the Licensor waives and/or agrees not to
+          assert any such rights held by the Licensor to the limited
+          extent necessary to allow You to exercise the Licensed
+          Rights, but not otherwise.
+
+       2. Patent and trademark rights are not licensed under this
+          Public License.
+
+       3. To the extent possible, the Licensor waives any right to
+          collect royalties from You for the exercise of the Licensed
+          Rights, whether directly or through a collecting society
+          under any voluntary or waivable statutory or compulsory
+          licensing scheme. In all other cases the Licensor expressly
+          reserves any right to collect such royalties.
+
+
+Section 3 -- License Conditions.
+
+Your exercise of the Licensed Rights is expressly made subject to the
+following conditions.
+
+  a. Attribution.
+
+       1. If You Share the Licensed Material (including in modified
+          form), You must:
+
+            a. retain the following if it is supplied by the Licensor
+               with the Licensed Material:
+
+                 i. identification of the creator(s) of the Licensed
+                    Material and any others designated to receive
+                    attribution, in any reasonable manner requested by
+                    the Licensor (including by pseudonym if
+                    designated);
+
+                ii. a copyright notice;
+
+               iii. a notice that refers to this Public License;
+
+                iv. a notice that refers to the disclaimer of
+                    warranties;
+
+                 v. a URI or hyperlink to the Licensed Material to the
+                    extent reasonably practicable;
+
+            b. indicate if You modified the Licensed Material and
+               retain an indication of any previous modifications; and
+
+            c. indicate the Licensed Material is licensed under this
+               Public License, and include the text of, or the URI or
+               hyperlink to, this Public License.
+
+       2. You may satisfy the conditions in Section 3(a)(1) in any
+          reasonable manner based on the medium, means, and context in
+          which You Share the Licensed Material. For example, it may be
+          reasonable to satisfy the conditions by providing a URI or
+          hyperlink to a resource that includes the required
+          information.
+
+       3. If requested by the Licensor, You must remove any of the
+          information required by Section 3(a)(1)(A) to the extent
+          reasonably practicable.
+
+  b. ShareAlike.
+
+     In addition to the conditions in Section 3(a), if You Share
+     Adapted Material You produce, the following conditions also apply.
+
+       1. The Adapter's License You apply must be a Creative Commons
+          license with the same License Elements, this version or
+          later, or a BY-SA Compatible License.
+
+       2. You must include the text of, or the URI or hyperlink to, the
+          Adapter's License You apply. You may satisfy this condition
+          in any reasonable manner based on the medium, means, and
+          context in which You Share Adapted Material.
+
+       3. You may not offer or impose any additional or different terms
+          or conditions on, or apply any Effective Technological
+          Measures to, Adapted Material that restrict exercise of the
+          rights granted under the Adapter's License You apply.
+
+
+Section 4 -- Sui Generis Database Rights.
+
+Where the Licensed Rights include Sui Generis Database Rights that
+apply to Your use of the Licensed Material:
+
+  a. for the avoidance of doubt, Section 2(a)(1) grants You the right
+     to extract, reuse, reproduce, and Share all or a substantial
+     portion of the contents of the database;
+
+  b. if You include all or a substantial portion of the database
+     contents in a database in which You have Sui Generis Database
+     Rights, then the database in which You have Sui Generis Database
+     Rights (but not its individual contents) is Adapted Material,
+
+     including for purposes of Section 3(b); and
+  c. You must comply with the conditions in Section 3(a) if You Share
+     all or a substantial portion of the contents of the database.
+
+For the avoidance of doubt, this Section 4 supplements and does not
+replace Your obligations under this Public License where the Licensed
+Rights include other Copyright and Similar Rights.
+
+
+Section 5 -- Disclaimer of Warranties and Limitation of Liability.
+
+  a. UNLESS OTHERWISE SEPARATELY UNDERTAKEN BY THE LICENSOR, TO THE
+     EXTENT POSSIBLE, THE LICENSOR OFFERS THE LICENSED MATERIAL AS-IS
+     AND AS-AVAILABLE, AND MAKES NO REPRESENTATIONS OR WARRANTIES OF
+     ANY KIND CONCERNING THE LICENSED MATERIAL, WHETHER EXPRESS,
+     IMPLIED, STATUTORY, OR OTHER. THIS INCLUDES, WITHOUT LIMITATION,
+     WARRANTIES OF TITLE, MERCHANTABILITY, FITNESS FOR A PARTICULAR
+     PURPOSE, NON-INFRINGEMENT, ABSENCE OF LATENT OR OTHER DEFECTS,
+     ACCURACY, OR THE PRESENCE OR ABSENCE OF ERRORS, WHETHER OR NOT
+     KNOWN OR DISCOVERABLE. WHERE DISCLAIMERS OF WARRANTIES ARE NOT
+     ALLOWED IN FULL OR IN PART, THIS DISCLAIMER MAY NOT APPLY TO YOU.
+
+  b. TO THE EXTENT POSSIBLE, IN NO EVENT WILL THE LICENSOR BE LIABLE
+     TO YOU ON ANY LEGAL THEORY (INCLUDING, WITHOUT LIMITATION,
+     NEGLIGENCE) OR OTHERWISE FOR ANY DIRECT, SPECIAL, INDIRECT,
+     INCIDENTAL, CONSEQUENTIAL, PUNITIVE, EXEMPLARY, OR OTHER LOSSES,
+     COSTS, EXPENSES, OR DAMAGES ARISING OUT OF THIS PUBLIC LICENSE OR
+     USE OF THE LICENSED MATERIAL, EVEN IF THE LICENSOR HAS BEEN
+     ADVISED OF THE POSSIBILITY OF SUCH LOSSES, COSTS, EXPENSES, OR
+     DAMAGES. WHERE A LIMITATION OF LIABILITY IS NOT ALLOWED IN FULL OR
+     IN PART, THIS LIMITATION MAY NOT APPLY TO YOU.
+
+  c. The disclaimer of warranties and limitation of liability provided
+     above shall be interpreted in a manner that, to the extent
+     possible, most closely approximates an absolute disclaimer and
+     waiver of all liability.
+
+
+Section 6 -- Term and Termination.
+
+  a. This Public License applies for the term of the Copyright and
+     Similar Rights licensed here. However, if You fail to comply with
+     this Public License, then Your rights under this Public License
+     terminate automatically.
+
+  b. Where Your right to use the Licensed Material has terminated under
+     Section 6(a), it reinstates:
+
+       1. automatically as of the date the violation is cured, provided
+          it is cured within 30 days of Your discovery of the
+          violation; or
+
+       2. upon express reinstatement by the Licensor.
+
+     For the avoidance of doubt, this Section 6(b) does not affect any
+     right the Licensor may have to seek remedies for Your violations
+     of this Public License.
+
+  c. For the avoidance of doubt, the Licensor may also offer the
+     Licensed Material under separate terms or conditions or stop
+     distributing the Licensed Material at any time; however, doing so
+     will not terminate this Public License.
+
+  d. Sections 1, 5, 6, 7, and 8 survive termination of this Public
+     License.
+
+
+Section 7 -- Other Terms and Conditions.
+
+  a. The Licensor shall not be bound by any additional or different
+     terms or conditions communicated by You unless expressly agreed.
+
+  b. Any arrangements, understandings, or agreements regarding the
+     Licensed Material not stated herein are separate from and
+     independent of the terms and conditions of this Public License.
+
+
+Section 8 -- Interpretation.
+
+  a. For the avoidance of doubt, this Public License does not, and
+     shall not be interpreted to, reduce, limit, restrict, or impose
+     conditions on any use of the Licensed Material that could lawfully
+     be made without permission under this Public License.
+
+  b. To the extent possible, if any provision of this Public License is
+     deemed unenforceable, it shall be automatically reformed to the
+     minimum extent necessary to make it enforceable. If the provision
+     cannot be reformed, it shall be severed from this Public License
+     without affecting the enforceability of the remaining terms and
+     conditions.
+
+  c. No term or condition of this Public License will be waived and no
+     failure to comply consented to unless expressly agreed to by the
+     Licensor.
+
+  d. Nothing in this Public License constitutes or may be interpreted
+     as a limitation upon, or waiver of, any privileges and immunities
+     that apply to the Licensor or You, including from the legal
+     processes of any jurisdiction or authority.

 Flatbread is probably the simplest sourdough bread to make.
 To make a flatbread no oven is required; all you need is a stove.

 Another trick to improve the texture of the flatbread is to

 during the baking process and thus make the bread fluffier.

+\label{subsec:flat-bread-framework}
+
+As explained above, if you are just getting started, making a flatbread is the
+easiest way to start making great bread at home. With just a
+few steps, you can stop buying bread forever. This works with
+any flour, including gluten-free options.
+

+      simple, requiring very little effort. This type of bread is especially
+      handy for busy bakers.}%
+  \label{fig:flat-bread-process}
+\end{flowchart}
+
+This is my go-to recipe that I~use to make bread whenever
+I~have little time or when I~am abroad. You can choose
+between two options:
+%
+\begin{enumerate}
+    \item A flatbread similar to a roti or naan bread
+    \item Sourdough pancakes.
+\end{enumerate}
+
+To get started prepare your sourdough starter. If it has not been used for a very
+long time, consider giving it another feed. To do so, simply take \qty{1}{\gram} of your
+existing sourdough starter and feed it with \qty{5}{\gram} of flour and \qty{5}{\gram} of water.
+If you do this in the morning, your sourdough starter will be ready in the evening. The
+warmer it is, the sooner it will be ready,  consider
+using warm water if it is very cold where you live.
+
+\begin{figure}[htb!]

+  \includegraphics[width=1.0\textwidth]{flat-bread-wheat}
+  \caption[Wheat flatbread]{A flatbread made with purely wheat flour. The
+      dough is drier at around \qty{60}{\percent} hydration. The drier dough
+      is a little harder to mix. As wheat contains more gluten, the dough
+      puffs up during the baking process.}
+\end{figure}
+
+This way you should have around \qty{11}{\gram} of sourdough ready in the evening. You will have
+the perfect quantity to make a dough for one person. In case you want to make more
+bread, simply multiply the quantities shown in
+Table~\ref{tab:flat-bread-ingredients}.
+
+Then in the evening simply mix the ingredients as shown in the table. Your dough
+is going to be ready in the morning. It's typically ready after 6--12~hours. If
+you use more sourdough starter it will be ready faster, conversely it will take
+longer if you use less. Try to aim for a fermentation time of 8--12~hours as
+by using your dough too soon, the flavor might not be as good. By using your
+dough later it might become a little more sour. The best option is to
+experiment and see what you personally like the most.
+
+After mixing the ingredients together cover the container, this prevents the
+dough from drying out and makes
+sure no fruit flies get access. A transparent container will be helpful
+when getting started. You can observe the dough more easily and see when
+it is ready.

+      made using teff flour.  The image has been provided by Charliefleurene
+      via Wikipedia.}
+\end{figure}
+
+If you used the flatbread option with less water, look at the size increase
+of your dough. It should have increased at least \qty{50}{\percent} in size.
+Also look out for bubbles on the sides of your container.
+
+When using the pancake recipe, look out for bubbles on the surface of your dough.
+In both cases use your nose to check the scent of your dough. Depending
+on your sourdough starter's microbiome your dough will have
+dairy, fruity, alcoholic notes or vinegary, acetic notes. Relying
+on the smell of your dough is the best way to judge whether your
+dough is ready or not. Timings are not reliable as they
+depend on your starter and the temperature. If your dough
+is ready too soon, you can now move it directly to the fridge and bake
+it at a later, more convenient time. The low temperature will halt the fermentation
+process\footnote{There are some exceptions. In some rare cases your starter
+might also work at lower temperatures. You might have cultivated microbes that work best at
+low temperatures. Nevertheless, fermentation
+is always slower the colder it gets. A fridge really helps to preserve the state
+of your dough.}
+and your dough will last for several days. The longer you wait, the more sour the
+bread is going to be. The fridge is a great option in case you want to
+take the dough with you when visiting friends. People are going
+to love you for the freshly baked flatbreads or pancakes. If you dare,
+you can also taste a little bit of your raw uncooked dough. It is likely
+going to taste relatively sour. I~do this frequently to better evaluate the
+state of my doughs.

+      microbes.  The image has been provided by Łukasz Nowak via Wikipedia.}
+\end{figure}
+
+If you are feeling lazy or don't have time, you could also use older sourdough starter
+to make the dough directly without any prior starter feedings. Your sourdough starter
+is going to regrow inside your dough. Remember that the
+final bread might be a bit more on the sour side as the balance of yeast to
+bacteria could be off. In the Table~\ref{tab:flat-bread-ingredients}
+I~recommended using around \qtyrange{5}{20}{\percent}
+of sourdough starter based on the flour to make the dough. If you were to follow
+this approach, just use around \qty{1}{\percent} and make the dough directly.
+The dough is probably going to be ready 24~hours later, depending on the temperature.
+
+If you want to make sweet pancakes, add some sugar and optional eggs to your dough
+now. A good quantity of eggs is around one~egg per \qty{100}{\gram} of flour.
+Stir your dough a little bit and it will be ready to be used. You'll
+have delicious sweet savory pancakes, the perfect combination. By
+adding the sugar now, you make sure that the microbes don't have
+enough time to fully ferment it. If you had added the sugar
+earlier, no sweet flavor would be left  12~hours later.
+
+To bake your dough heat your stove to medium temperature. Add a little bit of
+oil to the pan. This helps with heat distribution and ensures even cooking.
+With a spatula or a spoon place your dough in the pan. If your dough
+was sitting in the fridge, bake it directly. There is no need to wait for your
+dough to come to room temperature. If you have a lid,
+place it on your pan. The lid helps to cook your dough from the top.
+The evaporating water will circulate and heat up the dough's surface. When
+making a flatbread, make the dough around \qty{1}{\cm} thick. When using the
+pancake option, opt for around \qtyrange{0.1}{0.5}{\cm} depending on what you
+like.

+\end{figure}
+
+After 2--4~minutes flip over the pancake or flatbread. Bake it for the same
+time from the other side. Depending on what you like, you can wait a little
+longer to allow the bread to become a bit charred. The longer you
+bake your bread, the more of the acidity is going to evaporate. If your
+dough is a bit more on the sour side, you can use this trick to balance
+out the acidity. This really depends on which flavor you are looking for.
+
+When making a flatbread I~recommend wrapping the baked flatbreads in a kitchen
+towel. This way more of the evaporating humidity stays inside of your bread,
+making sure your flatbreads stay nice and fluffy for a longer period after the
+bake. A similar strategy is used when making corn tortillas.
+

+\chapter{Glossary}%
+\label{ch:Glossary}
+
+\begin{quoting}
+This glossary provides definitions and explanations for terms frequently
+used in bread making. Understanding these terms is essential for both
+novice and experienced bakers aiming to master the art and science of
+bread making. The glossary is arranged alphabetically for easy reference.
+\end{quoting}
+
+\begin{description}
+
+\item[Acetic Acid] A type of organic acid produced by hetero fermentative lactic
+acid bacteria and acetic acid bacteria during fermentation. It gives sourdough bread
+its characteristic tangy flavor and helps to preserve the bread by lowering its pH.
+The flavor of acetic acid has a more vinegary profile.
+
+\item[Aliquot jar] A small piece of dough extracted after creating initial
+dough strength.  The aliquot jar is used to monitor the dough's fermentation progress.
+It's important to ensure the dough's water temperature in the aliquot matches
+your room temperature for accurate readings. Be mindful that the aliquot
+jar may not be as effective if there are significant temperature
+fluctuations in your kitchen. This is because the small dough sample in
+the aliquot can heat up or cool down faster than the main dough mass,
+potentially impairing its ability to accurately monitor fermentation.
+It's crucial to use a cylindrical-shaped aliquot container to properly judge
+the dough's size increase.
+
+\item[All Purpose Flour] A general flour that’s balanced to make breads and also
+cakes. In Germany this is type~550.
+
+\item[Alpha-amylase] A type of amylase that breaks down starch molecules into
+shorter fragments, producing maltose and some glucose.
+
+\item[Alveograph] A device used primarily in the evaluation of wheat flour's
+baking quality. The alveograph assesses the dough's rheological properties,
+particularly its extensibility and resistance to extension, by inflating a piece
+of dough like a balloon until it bursts. The resulting chart, or \emph{alveogram},
+displays a curve that represents the balance between the dough's elasticity and
+extensibility. Specific parameters derived from the curve, such as the P (pressure
+required to inflate the dough) and L (extensibility of the dough), provide invaluable
+insights to bakers and millers regarding the flour's potential performance in
+bread-making. By analyzing the alveogram, professionals can make informed decisions
+about the suitability of a flour for certain baking applications, as well as
+potential blending needs with other flours.
+
+\item[Alveoli] (singular Alveolus) The little pockets that form the crumb,
+formed by the gluten matrix trapping carbon dioxide.
+
+\item[Amylase] An enzyme that breaks down starches into simpler sugars, facilitating
+the fermentation process in beer and bread making. When making beer the temperature
+of the brew is kept for extended periods at certain temperatures to ensure that most
+starches are broken down to sugars. These sugars are then consumed by the microbes
+during the fermentation process.
+
+\item[Autolyse] A process where flour and water are mixed and then left to rest
+before adding other ingredients. This activates enzymes such as amylase and protease.
+By doing so the bulk fermentation time is shortened and the final loaf will have
+better properties. The browning of the loaf becomes better and the crumb fluffier.
+An autolyse is recommended when using a high percentage of starter to inoculate the
+dough (>~\SI{20}{\percent}). An alternative easier approach can be the fermentolyse.
+
+\item[Bacteria] Unicellular microorganisms that exist in diverse forms and
+habitats. They play crucial roles in various natural processes, especially in food
+preparation like sourdough fermentation. Lactic and acetic acid bacteria, in particular,
+are pivotal in the sourdough process, contributing to its distinct taste and texture.
+Some bacteria are beneficial, aiding in digestion or producing vitamins, while others
+can be harmful and cause diseases.
+
+\item[Baker’s Math] Baker’s math is a ratio based system of sharing recipes,
+making them easily scalable. It’s based on the total weight of the flour in a formula,
+where each ingredients weight is divided by the flours weight to give a percentage.
+For \SI{500}{\gram} of flour you could be using \SI{60}{\percent} of water (\SI{300}{\gram}),
+\SI{10}{\percent} of starter (\SI{50}{\gram}) and \SI{2}{\percent} of salt (\SI{10}{\gram}).
+
+\item[Baker’s percentage] See Baker’s math.
+
+\item[Baking] The final, transformative step in bread making wherein dough is
+exposed to high temperatures, causing a series of chemical and physical reactions
+that result in a finished loaf of bread. During the baking stage:
+
+\begin{enumerate}
+\item \emph{Yeast Activity \& Oven Spring:} In the initial phase of baking, the
+temperature inside the dough rises, increasing yeast activity. This results in rapid
+carbon dioxide production, leading to what bakers refer to as \emph{oven spring}, or the
+rapid rise of the loaf.
+
+\item \emph{Protein Coagulation:}  As the temperature continues to climb, the proteins
+in the dough, primarily gluten, begin to coagulate or set, which gives the bread its
+structure.
+
+\item \emph{Starch Gelatinization:}  Starches absorb water and swell, eventually
+gelatinizing. This process contributes to the crumb structure of the bread.
+
+\item \emph{Caramelization \& Maillard Reaction:}  The crust of the bread browns due
+to two primary reactions: caramelization of sugars and the Maillard reaction between
+amino acids and reducing sugars. This not only affects the appearance but also imparts
+a distinctive flavor and aroma to the bread.
+
+\item \emph{Evaporation of Acids:} Some acids produced during fermentation evaporate at
+certain temperatures during baking. This evaporation can influence the final flavor
+profile of the bread, making it less tangy than the unbaked dough. By extending the
+baking time the acids become less concentrated and the dough can lose some of its tang.
+
+\item \emph{Moisture Evaporation:} Water in the dough turns to steam and begins to
+evaporate. The steam contributes to the oven spring and also helps in gelatinizing
+the starches.
+
+\item \emph{Crust Formation:} The outer layer of the dough dries out and hardens to
+form a crust, which acts as a protective barrier, keeping the inner crumb moist.
+\end{enumerate}
+
+\item[Banneton] A wicker basket used to shape and support dough during its final
+proof. The bannetons are typically made out of rattan or wood pulp. An alternative
+DIY solution is to use a bowl with a kitchen towel inside. While resting inside of
+the banneton the dough’s surface dries out and becomes easier to score before baking.
+
+\item[Bassinage method] A bread making technique involving the staged addition of water
+to the dough. Initially, the dough is mixed to a lower hydration level,
+allowing gluten bonds to form more effectively. Once these gluten structures
+are established, additional water is gradually incorporated through further
+kneading. This method enhances the dough's extensibility, especially beneficial
+when working with lower-gluten flours. By employing the bassinage method,
+bakers can achieve a dough that is both strong and extensible.
+
+\item[Bench Rest] A short resting period given to the dough after preshaping
+allowing the gluten to relax a little bit and making shaping easier. Most people
+bench rest for 10 minutes up to an hour. The bench rest becomes especially important
+when making pizza doughs. Without an extended bench rest the dough is too elastic and
+can not be shaped.
+
+\item[Beta-amylase] An enzyme that further breaks down the starch fragments
+produced by alpha-amylase into maltose.
+
+\item[Bread Flour] A flour that is perfect for sourdough bread making. It features
+a higher amount of gluten and can thus ferment for a longer period of time.
+
+\item[Brühstück] A German baking technique similar to a scald. It translates as
+\emph{boil piece}. Hot or boiling water is poured over whole grain flour or crushed grains,
+then cooled and mixed with the main dough. This process helps in moisture retention
+and can enhance the flavor and texture of the final bread. Also see \emph{scald}.
+
+\item[Bulk Fermentation] The initial rising period after mixing all the
+    ingredients.  The dough is typically allowed to rise until it increases to
+    a certain volume. The volume of increase depends on the flour that is
+    used. When baking with wheat flour the gluten amount of the flour is the
+    deciding factor. The more gluten your flour has (protein) the longer you
+    can bulk ferment. A longer bulk fermentation improves the flavor and
+    texture of the final bread. It becomes tangier and fluffier. You can aim
+    for a \SI{25}{\percent} size increase of your dough and then slowly
+    increase this to find your flour's sweet spot. This is highly dependent
+    from flour to flour. When using low gluten flour like rye you need to be
+    careful as the longer fermentation can create a too sticky dough which
+    collapses and does not hold its shape anymore.
+
+\item[Cake Flour] Cake flour is a light, finely milled flour with a lower
+    protein content than all-purpose flour. It's ideal for tender baked goods
+    like cakes, cookies, and pastries.
+
+\item[Coil fold] A special stretch and folding technique. The coil fold is
+very gentle on the dough and is thus excellent throughout the bulk fermentation.
+By applying the coil fold the dough strength is improved by minimizing damage
+to the dough structure.
+
+\item[Crumb] The inner texture of the bread, which is characterized by the size,
+shape, and distribution of the holes (or \emph{alveoli}). It's what's inside once you slice
+a loaf of bread open. A \emph{tight crumb} refers to bread with small, evenly distributed
+holes, while an \emph{open crumb} has larger, more irregular holes.
+
+\item[Diastatic Malt] Malted grain that has been dried and then ground into a powder.
+This malt contains enzymes that can break down starches into sugars, which can be
+beneficial in the fermentation process for bread. When added to dough, it can improve
+the bread's flavor, color, and shelf life.
+
+\item[Discard] The portion of sourdough starter that is removed and not fed when
+maintaining the starter. This is often done to prevent the starter from becoming too
+large and unmanageable. Discard can be used in various recipes or thrown away.
+
+\item[Dividing] The process of breaking the dough mass into smaller pieces,
+typically to shape into individual loaves or portions.
+
+\item[Dough Hydration] Expressed as a percentage, it's the amount of water in a
+dough relative to the amount of flour. A higher hydration dough will be wetter and
+stickier, while a lower hydration dough will be firmer. For example, a dough
+with \SI{500}{\gram} of flour and \SI{375}{\gram} of water has a hydration of
+\SI{75}{\percent}
+
+\item[Dough Strength] Refers to the dough's resilience, elasticity, and structure.
+A strong dough can be stretched without tearing and holds its shape well. This is
+largely influenced by the flour's protein content and the development of the gluten
+network.
+
+\item[Dutch Oven] A heavy-duty pot with a tight-fitting lid, often made of cast
+iron. It's used in baking to trap steam during the initial phase of baking, helping
+to create a crusty exterior on bread.
+
+\item[Elasticity] A property of dough that describes its ability to return to
+its original shape after being stretched or deformed. It's influenced by the flour's
+protein content and the development of the gluten network.
+
+\item[Extensibility] Refers to the dough’s ability to be stretched or extended
+without tearing. It's the opposite of elasticity and is desirable in certain types
+of breads, like ciabatta, that have a more open crumb structure.
+
+\item[Feed] The act of adding fresh flour and water to maintain a sourdough
+starter. Regular feeding keeps the starter active and healthy.
+
+\item[Fermentation] The metabolic process by which microorganisms such as yeast
+and bacteria convert carbohydrates (like sugars) into alcohol or acids. In bread
+making, this produces carbon dioxide which causes the dough to rise.
+
+\item[Fermentolyse] Using a small amount of starter to slow fermentation.
+It's a method where fermentation and autolyse are combined. Typically around \SI{10}{\percent}
+of starter is used for the fermentolyse. The flour, water and starter are mixed
+together. By adding the starter early the dough becomes more extensible and easier
+to handle.
+
+\item[Finger poke test] The finger poke test is a simple yet effective way to
+check if your sourdough bread is ready to bake. After the final rise, lightly
+flour your finger and gently press about half an inch into the dough.
+If the dough springs back slowly and leaves a slight indentation, it's perfect
+and ready for the oven. If it springs back quickly, it needs more time to rise.
+However, if the dough collapses or doesn't spring back at all, it may be
+over fermented.
+
+\item[Float test] The float test is a technique for assessing the readiness
+of a sourdough starter. To perform this test, take a small sample of
+your starter and gently place it in a glass of water. The outcome
+of this test can provide insights into your starter's fermentation stage.
+
+\begin{itemize}
+\item[] \emph{Positive result:} If your starter effortlessly floats on the
+surface of the water, it's a clear indication that it has reached its peak
+of fermentation and is ready to be used as a leavening agent in your dough.
+This buoyancy is a result of the carbon dioxide gas produced during
+the active fermentation process.
+\item[] \emph{Negative result:} Conversely, if your starter sinks to the
+bottom of the glass, it suggests that it's not quite ready yet.
+This indicates that the fermentation process has not progressed
+sufficiently for optimal leavening power.
+\end{itemize}
+
+It's worth noting that while the float test is a reliable indicator
+for wheat-based sourdough starters, it may not be as effective for non-wheat
+starters. This is because the gas generated during fermentation in non-wheat
+starters tends to escape more readily, making it less buoyant. For non-wheat
+starters, a more accurate approach involves observing the presence of
+bubbles in your starter jar and assessing its aroma. A mature starter should
+emit a mildly sour, but not overly pungent, scent.
+
+\item[Fool’s Crumb] A term used to describe a crumb structure that has several
+large pockets or holes, rather than an even distribution of smaller holes. This
+isn't necessarily a desired feature, as it can indicate uneven fermentation or
+improper shaping techniques.
+
+\item[Gluten] A protein complex formed from gliadin and glutenin, found in wheat
+and some other grains. It provides elasticity and strength to the dough when
+properly aligned and developed. During the course of the bulk fermentation much of
+the gluten is degraded by the protease enzyme and lactic acid bacteria.
+
+\item[Homogenizing] The act of creating a consistent and uniform mixture. For
+flours like einkorn and rye, where gluten alignment isn't the main goal, kneading
+ensures that the dough achieves this homogeneous consistency.
+
+\item[Hooch] A liquid layer that sometimes forms on top of a sourdough starter.
+It's an indication that the starter is hungry and needs feeding. It acts as a
+barrier shield and prevents the starter from catching mold. It can be mixed right
+back into the starter or extracted to make hot sauces.
+
+\item[Kneading] The manual or mechanical process of working dough to develop gluten
+in wheat and spelt-based breads, or to homogenize the dough mass in flours like
+einkorn or rye.
+
+\item[Kochstück] When making a Kochstück, the flour or grains are heated
+together with the fluid. The mixture needs to be stirred while heating up
+to prevent clumping and burning it.
+
+\item[Lactic Acid] Another organic acid produced by lactic acid bacteria during
+fermentation. It imparts a mild tangy yogurty flavor to sourdough bread and, along
+with acetic acid, contributes to the bread's overall acidity.
+
+\item[Levain] See Sourdough starter.
+
+\item[Maillard Reaction] The Maillard reaction is one of the causes of food browning
+during cooking. The reaction occurs between reducing sugars and amino acids, and
+depending on the initial reactants and cooking conditions can produce a wide variety
+of end products with different tastes and aromas. Maillard reactions occur readily
+above \SI{150}{\celsius}, although will still occur much more slowly below that
+temperature. Optimal reaction rate occurs between \pHvalue{6.0} to \pHvalue{8.0},
+although it favors alkaline conditions.
+
+\item[Maltose] A sugar produced from the enzymatic breakdown of starch by amylases.
+It's a primary food source for yeast during fermentation.
+
+\item[Non-diastatic Malt] Malted grain that has been dried at higher temperatures,
+deactivating its enzymes. It's used primarily for flavor and color in bread making.
+Amylase and protease become degraded at temperatures higher than 50°C.
+
+\item[Oven Spring] The rapid rise of the dough in the oven during the early stages
+of baking due to the expansion of trapped gases and water.
+
+\item[Over Fermenting] A common problem when making wheat or spelt doughs. When the
+dough is fermented for too long most of the gluten in the dough is broken down. The
+resulting dough is very sticky. The final bread will be very flat and lose some of its
+typical texture. The crumb structure features many tiny pockets of air. A lot of the
+trapped gasses can diffuse out of the dough during baking. If you notice this during
+bulk fermentation it is advised to place the loaf inside of a loaf pan and then bake
+it after a 30 to 60 minute rest.
+
+\item[Over Proofing] The same as over fermenting, however happening during the
+proofing stage.
+
+%Hack to make sure there is a carriage return
+\item[pH] A measure of the acidity or alkalinity of a solution. The pH scale
+ranges from 0 to 14, where a pH value of 7 is neutral. Solutions with a pH value below
+7 are acidic, while those with a pH above 7 are alkaline or basic. Fermented
+foods with a pH below 4.2 are generally considered foodsafe. A pH meter can be
+used to monitor your sourdough bread's fermentation progress.
+
+\item[P/L Value] A critical parameter derived from the alveograph test, the P/L
+value represents the ratio of the dough's tenacity (P) to its extensibility (L).
+Specifically:
+
+\begin{itemize}
+    \item[] \emph{P (Pressure)} refers to the pressure required to inflate the
+        dough during the alveograph test. It indicates the dough's resistance
+        to deformation or its strength.
+    \item[] \emph{L (Length)} represents the extensibility of the dough, or
+        how far it can be stretched before tearing.
+\end{itemize}
+The P/L ratio provides insights into the balance between the dough's elasticity and
+extensibility:
+%
+\begin{itemize}
+    \item[] \emph{Low P/L Value} indicates a dough that is more extensible
+        than resistant. This means the dough can be stretched easily, making
+        it suitable for certain products like pizza or ciabatta.
+    \item[] \emph{High P/L Value} suggests a dough that has more strength than
+        extensibility. Such a dough is more resistant to deformation, which
+        can be preferable for products that require good volume and structure,
+        like certain types of bread.
+\end{itemize}
+The P/L value helps bakers and millers determine the suitability of a flour for
+specific baking applications. Adjustments in flour blends or baking processes might
+be made based on this ratio to achieve desired bread characteristics.
+
+\item[Preferment] A mixture of a proportion of the doughs ingredients which is
+allowed to ferment before being added to the final bread dough. These can include
+sourdough, poolish, biga, pâte fermentée, or a general sponge.
+
+\item[Preshaping] When dividing your large dough mass into smaller portions you end
+up having non-uniform pieces of dough. This makes shaping much harder because the
+resulting shaped dough will not be uniform. For this reason bakers drag the tiny dough
+pieces over the surface of the counter to create more uniform looking dough balls.
+
+\item[Proof] The final rise of the shaped dough before baking.
+
+\item[Protease] An enzyme that breaks down proteins, including gluten, into smaller
+peptide chains and amino acids. In the context of bread making, protease activity can
+both benefit and challenge bakers. Moderate protease activity can make dough more
+extensible, which can be helpful in some bread-making processes. However, excessive
+protease activity can weaken the gluten network, leading to doughs that are slack,
+sticky, and challenging to handle, and may result in breads with poor volume and
+structure. Factors such as fermentation time, dough temperature, and the source of the
+flour can influence protease activity in bread doughs. In sourdoughs, longer
+fermentation times, particularly at warmer temperatures, can lead to higher protease
+activity, as the acidic conditions activate cereal proteases. Flour from sprouted
+grains or malted grains can have higher protease activity due to the sprouting or
+malting process. Understanding and controlling protease activity is crucial in
+achieving desired bread quality and handling characteristics.
+
+\item[Pullman Loaf] A type of bread loaf characterized by its perfectly
+    rectangular shape and soft, fine crumb. It is baked in a special lidded
+    pan called a Pullman pan or \emph{pain de mie} pan. The lid ensures that
+    the bread rises in a perfectly straight shape, without the domed top
+    characteristic of other bread loaves. Pullman loaves are often sliced very
+    thin and are popular for making sandwiches.
+
+\item[Retarding] The process of slowing down fermentation during the proofing
+stage by placing the dough in a colder environment, typically a refrigerator. This aids
+bakers in scheduling, allowing them to have more control over when to bake their breads,
+especially in large-scale bakeries where timing is essential to serve freshly baked bread
+to early morning customers. While scheduling is the main reason, some bakers also assert
+that retarding can enhance the bread's overall flavor profile. Also known as
+fridge-proofing.
+
+\item[Rye] A type of grain used in baking. Due to its low gluten content, breads
+made solely from rye flour tend to be dense. However, rye has a unique flavor and
+many health benefits, so it's often combined with wheat flour in baking. Pure rye
+breads are typically made with a sourdough process to help the dough rise.
+
+\item[Scald] A method where boiling water is poured over flour, grains, or other
+ingredients and then allowed to cool. In baking, this process can gelatinize the
+starches in the flour or grains, resulting in a dough that retains moisture better,
+provides a softer crumb, and potentially extends the bread's shelf life. Additionally,
+scalding can help inactivate certain enzymes which can be detrimental to the dough's
+quality. The scalding technique can also enhance the overall flavor and aroma of
+the bread, bringing out more pronounced grainy notes and reducing bitterness
+sometimes found in certain whole grains.
+
+\item[Scoring] Cutting the surface of the bread dough before it's baked. This
+allows the dough to expand freely in the oven, preventing it from bursting in
+unpredictable ways. It also provides a controlled aesthetic to the finished loaf.
+
+\item[Sift] To pass flour or another dry ingredient through a sieve to
+    remove lumps and aerate it.
+
+\item[Soaker] A mixture of grains or seeds with water that is left to soak overnight (or for a
+specified amount of time) before being incorporated into bread dough. This helps to
+soften and hydrate the grains or seeds (sesame, pumpkin, \etc{}), making them
+easier to integrate into the dough and
+providing a moister crumb in the finished bread.
+
+\item[Sponge] A type of preferment, a sponge is a wet mixture of flour, water, and
+yeast that is allowed to ferment for a certain period before being incorporated into
+the final dough.
+
+\item[Starter] A fermented mixture of flour and water containing a colony of
+microorganisms including wild yeast and lactic acid bacteria. It's used to leaven
+bread.
+
+\item[Straight Dough] A bread-making method where all ingredients are mixed
+together at once, without the use of a preferment.
+
+\item[Stretch and Fold] S\&F is a technique used during the bulk fermentation phase
+to strengthen the dough and help align the gluten structure. Instead of traditional
+kneading, the dough is gently stretched and then folded over itself. This process is
+typically repeated multiple times throughout bulk fermentation.
+
+\item[Tangzhong] A Chinese technique for bread-making, similar to the
+Japanese yudane method. It involves cooking a small portion of the flour
+with water (or milk) to create a slurry or roux. This process, which can be seen as a
+variant of scald, gelatinizes the starches in the flour, resulting in breads
+that are softer, fluffier, and have improved moisture retention. Once cooled, the
+Tangzhong is mixed with the remaining ingredients to produce the final dough.
+
+\item[Tight Crumb] Refers to a bread crumb (the soft inner part of the bread) that
+has small, uniform air holes.
+
+\item[Wild Yeast] Naturally occurring yeast, present in the environment and on the
+surface of grains, used in sourdough fermentation as opposed to commercial yeast.
+There’s wild yeast on almost any surface of plants. The wild yeasts live in symbiosis
+with the plant providing a shield against pathogens and receiving sugars from the
+photosynthesis of the plant in return. When the plant becomes weak the wild yeasts
+can become parasitic and consume the host.
+
+\item[W-Value] A parameter representing the strength of flour in terms of its
+baking quality. The W-value, derived from the Chopin Alveograph test,
+measures the energy required to blow a bubble with the dough until it bursts.
+It is a direct indicator of the flour's ability to withstand the fermentation
+and baking processes. A higher W-value typically indicates a stronger
+flour, suitable for breads with high volume and longer fermentation times.
+Conversely, a lower W-value suggests a weaker flour, better suited for
+products requiring less structure, like cakes and pastries.
+
+\item[Yeast] Microorganisms that ferment the sugars present in the dough, producing
+carbon alcohol, carbon dioxide and heat; thereby causing the dough to rise.
+
+\item[Yudane] A Japanese method of bread-making which involves the preparation
+of a starter by mixing boiling water with bread flour in a specific ratio, typically 1:1
+by weight. After mixing, the paste is left to cool to room temperature and then
+refrigerated overnight. The next day, it is combined with the remaining ingredients
+to make the dough. The Yudane method, essentially a type of scald, helps in
+improving the texture of the bread, making it softer and fluffier while also enhancing
+its shelf life.

+Whoever comes first, bacteria or archaea, remains debated. For three

+stone mill, known as a \emph{gristmill}. These mills advanced flour production
+from a few kilograms up to several metric tons per day~\cite{history+mills}.
+
+These early mills featured horizontal paddle wheels, eventually termed
+\emph{Norse wheels} due to their prevalence in Scandinavia.  The paddle wheels
+connected to a shaft, which, in turn, linked to the central runner stone for
+grinding. Water flow propelled the paddle wheels, transferring the grinding
+force to the stationary \emph{bed}, typically a stone of similar size and
+shape. This design was straightforward, avoiding the need for gears. However,
+it had a limitation: the stone's rotation speed relied on water volume and
+flow rate, making it most suitable for regions with fast-flowing streams,
+often found in mountainous areas~\cite{mills+scandinavia}.
+
+In the year \num{1680}, a remarkable scientist by the name of
+Antonie~van~Leeuwenhoek introduced a groundbreaking innovation that would
+forever alter our understanding of the microscopic world and ultimately bread
+making.  Van~Leeuwenhoek, a master of lens craftsmanship, possessed an
+insatiable fascination with realms invisible to the naked eye. His pioneering
+work birthed the first modern microscope.  What set Van~Leeuwenhoek apart was
+the exceptional quality of his lenses, capable of magnifying tiny
+microorganisms by an astounding factor of \num{270}.  Driven by an unrelenting
+curiosity to unveil the unseen, he embarked on a journey of exploration. He
+scrutinized flies, examined lice-infested hair, and ultimately turned his gaze
+toward the tranquil waters of a small lake near Delft.
+
+In this serene aquatic habitat, he made astonishing observations, discovering
+algae and minuscule, dancing creatures hitherto hidden from human perception.
+Eager to share his revelatory findings with the scientific community,
+Van~Leeuwenhoek faced skepticism, as it was difficult to fathom that someone
+had witnessed thousands of diminutive, dancing entities—entities so tiny that
+they eluded the human eye.
+
+Undeterred by skepticism, he continued his relentless pursuit of the unseen,
+directing his lens towards a brewer's beer sludge. In this obscure medium,
+Van~Leeuwenhoek made history by becoming the first human to lay eyes upon
+bacteria and yeast, unraveling a previously concealed world that would
+revolutionize our understanding of microbiology~\cite{Yong+2017+Leeuwen}.
+
+At the same time brewers would start to experiment with utilizing the muddy
+leftovers of the beer fermentation to start making doughs. They would notice
 that the resulting bread doughs were becoming fluffy and compared
 to the sourdough process would lack the acidity in the final product.

+Many of the above-listed mix-ins can't be pinpointed to a single category. They

+\end{figure}

 Mix-ins affect the structure of the dough. One aspect is the impact on
 hydration. Some mix-ins absorb a lot of water when added to the dough, so you
 have to increase the amount of water to achieve the same dough consistency.
 The other impact is on the gluten network. Bits and chunks disrupt the gluten

 used. A good rule of thumb is to add \qtyrange{10}{20}{\percent} of the amount
 of flour in most mix-ins, reduced to around \qtyrange{1}{5}{\percent} of the
 amount of flour for spices.
 
 An important factor is also the mix-in's behavior during baking. Particularly
 chunks may bake differently than dough, and either melt (cheese) leaving holes

 \section{Techniques}
-Adding mix-ins into the dough is just the simplest approach. There are other,
-more advanced ways to include them into a loaf.
 
-\subsection{Covering the crust}
+Adding mix-ins to the dough is just the simplest approach. Add the mix-ins
-This works best for either powders or small bits. Spread the mix-in in a flat
+directly when you knead the dough. After the first kneading wait for 30
-container, wet the surface of the loaf, and dip it into the mix-in right
+minutes to see if the dough has enough or too much water. In the case of
-before baking.
+whole-soaked berries (\eg~rye or wheat) chances are that the berries will
+release some water and make the dough wetter. In this case, you will want to
+add a bit more flour to the dough to compensate for the high hydration.
 
-This does not work for all mix-ins, as some can't handle the high temperatures
+\subsection[Incorporating seeds into the dough]{What is the best stage to
-during baking and char. Most commonly done with seeds (\eg, sesame).
+incorporate inclusions (seeds) into the dough?}%
+\label{subec:incorporate-seeds}
+
+You can include seeds directly at the start when mixing the dough. If you use
+whole seeds such as wheat or rye kernels, soak them in water overnight and
+then rinse them before adding them to the dough. This makes sure that they are
+not crunchy and are soft enough when eating the bread. If you forgot to soak
+them you can cook the seeds for 10~minutes in hot water. Rinse them with cold
+water before adding them to your dough.
+
+If you want to sweeten the dough, your best option is to add sugar during the
+shaping stage. Sugar added too early in the process typically gets fermented
+until none of it remains. Adjust your shaping technique a little bit and
+spread your sugar mixture over a flattened-out dough. You can then roll the
+dough together, incorporating layers of sugar.
+
+\subsection{Adding before shaping}
+
+\begin{figure}[htb!]
+  \centering
+  \includegraphics[width=\textwidth]{apple-swirl}
+  \caption[Apple swirl buns]{A great technique is to add some of your mix-ins
+      directly before shaping. In this case, a mixture of apples, cinnamon and
+      brown sugar was applied. Proceed and roll the dough together. Afterward
+      cut the roll into smaller pieces using a sharp knife, dough scraper or
+      dental floss. Place each piece of dough next to each other in a greased
+      bowl to allow them to be proofed.  Proceed and bake as you would
+      normally do. The benefit of this technique is that the mix-ins will not
+      be fermented. This is typically required in the case of sugar since you
+      want the final baked goods to feature sweetness. If included upon
+      initial mixing most of the sugar would be fermented and the bread would
+      not taste sweet.}%
+  \label{fig:apple-swirl}
+\end{figure}
+
+Another approach is to lay the dough out flat after the bulk fermentation.
+Then using a spatula spread your ingredient over the flat dough. Continue with
+your regular shaping and/or roll up the dough. When creating a roll you can
+use a sharp knife to cut the dough, dental floss works great too. Afterward,
+place the tiny swirls in a container to let them proof and become fluffier.
+This is an excellent way to add sweet mix-ins as the microbes will not ferment
+them. When adding sugar to the initial dough it will be fermented and the
+resulting dough will not taste sweet (depending on the fermentation duration).
+This approach is excellent for garlic/cheese rolls, garlic/herb rolls, and
+cinnamon rolls
+
+\subsection{Covering the surface}
+
+\begin{figure}[htb!]
+  \centering
+  \includegraphics[width=\textwidth]{surface-seeds}
+  \caption[Surface seeds]{These are chop buns which are created by chopping
+    up a retarded dough into smaller pieces before baking. Then each piece of
+    dough is quickly dumped in water and then rolled in a bowl of seeds.
+    Afterward, the dough is directly baked in the preheated oven. These
+    coverings add superb additional flavor and can be adjusted depending on
+    your preference. I love adding a mixture of sunflower, flax, and
+    sesame seeds.}%
+  \label{fig:surface-seeds}
+\end{figure}
+
+This works best for either powders or small bits. After shaping wrap your
+coverings on the dough's surface. This works great too when covering your
+banneton or loaf pan with seeds or oats. When using a loaf pan or banneton
+these coverings also help to make the container stick less.
+
+Another approach commonly used with buns is to wet the surface or dump the
+dough in water. Afterward, dip the wet piece of dough into your bowl of
+mix-ins.  This does not work for all mix-ins, as some can't handle the high
+temperatures during baking and char. Most commonly done with seeds
+(\eg~sesame, oats, flax-seed).
 
 \subsection{Swirled colors}
 Mix-ins that change the color of the dough bring the opportunity for even more
-creativity.
+creativity by merging the dough before shaping.
 
-Separate the dough before adding a colorful ingredient. Combine the two (or

+\subsubsection*{Instructions}
+\begin{description}
+\item[Prepare the dough] In a large mixing bowl, combine the flour and water.
+    Mix until you have a shaggy dough with no dry spots.
+
+    Add the sourdough starter and salt to the mixture. Incorporate them
+    thoroughly until you achieve a smooth and homogenized dough.
+
+\item[Fermentation:] Cover the bowl with a lid or plastic wrap. Allow the dough
+    to rest and ferment until it has increased by at least \qty{50}{\percent}
+    in size.  Depending on the temperature and activity of your starter, this
+    can take anywhere from 4 to 24~hours.
+
+\item[Cooking preparation:] Once the dough has risen, heat a pan over medium
+    heat.  Lightly oil the pan, ensuring to wipe away any excess oil with a
+    paper towel.
+
+\item[Shaping and cooking:] With a ladle or your hands, scoop out a portion of
+    the dough and place it onto the hot pan, spreading it gently like a
+    pancake.
+
+    Cover the pan with a lid. This traps the steam and ensures even cooking
+    from the top, allowing for easier flipping later.
+
+    After about 5~minutes, or when the bottom of the flatbread has a
+    golden-brown crust, carefully flip it using a spatula.
+
+    \emph{Adjusting cook time.} If the flatbread appears too dark, remember to
+    reduce the cooking time slightly for the next one.  Conversely, if it's
+    too pale, allow it to cook a bit longer before flipping.
+
+    Cook the flipped side for an additional 5~minutes or until it's also
+    golden brown.
+
+\item[Storing:] Once cooked, remove the flatbread from the pan and place it on
+    a kitchen towel. Wrapping the breads in the towel will help retain their
+    softness and prevent them from becoming overly crisp.  Repeat the cooking
+    process for the remaining dough.
+
+\item[Serving suggestion:] Enjoy your sourdough flatbreads warm, paired with
+    your favorite dips, spreads, or as a side to any meal.
