-\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.

 \section{Techniques}
 
 Adding mix-ins to the dough is just the simplest approach. Add the mix-ins
-directly when you knead the dough. After the first kneading wait for 30 minutes to see
-if the dough has enough or too much water. In the case of 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.

+add a bit more flour to the dough to compensate for the high hydration.
+
+\subsection[Incorporating seeds into the dough]{What is the best stage to
+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!]

   \includegraphics[width=\textwidth]{apple-swirl}
   \caption[Apple swirl buns]{A great technique is to add some of your mix-ins

-  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

+  \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 mixins 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

+\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.
