-(the transition between these categories is somewhat fuzzy):

   \item Texture: Significantly changes the feeling in the mouth when eaten.
       Examples: Cheese (gummy), seeds (crunchy), olives (squishy chunks).
 \end{itemize}
 
+Many of the above-listed mix-ins can't be pinpointed to a single category. They
+change multiple aspects of the final bread at the same time.

+\begin{figure}[htb!]

+\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
-network, and may reduce the rise. All of this depends on the amount of mix-ins
+network and may reduce oven spring during baking. All of this depends on the amount of mix-ins
 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

 regular bread flour. Different flours change the taste of the bread and
 usually moderately affect the color.
 \begin{itemize}
   \item Whole wheat flour (substitute any amount, makes the bread taste more
       complex, nutty)
   \item Rye flour (very hearty, nutty, malty taste)
-  \item Semolina (supports mediterranean flavors)

+    a great addition when making quicker yeast-based doughs.

   \item Cocoa (replace \qty{10}{\percent} of the flour for a black loaf, goes
       great with sweet toppings)

 \subsection{Liquids}

 \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 minutes to see
-container, wet the surface of the loaf, and dip it into the mix-in right
+if the dough has enough or too much water. In the case of whole-soaked berries
-before baking.
+(\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{Adding before shaping}
-during baking and char. Most commonly done with seeds (\eg, sesame).
+
+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
+
+\subsection{Covering the surface}
+
+\begin{figure}[htb!]
+  \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.}%
+\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 wetted piece of dough into your bowl of
+mixins.  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

+of dough before the last folding, just before shaping. This way the colored

+layered featuring different colors, textures, and flavors.}
