\section{Simple flatbread recipe}%
\label{section:flat-bread-recipe}
By following the steps outlined in this section.
you'll be introduced to a versatile bread that's perfect for a myriad of
culinary applications. Whether you're scooping up a savory dip,
wrapping a flavorful filling, or simply savoring a piece with a drizzle
of olive oil, these flatbreads are sure to impress.
\textbf{Ingredients:}
\begin{enumerate}
\item 400 grams flour (wheat, rye, corn, whatever you have at hand)
\item 320 grams water, preferably at room temperature
\item 80 grams active sourdough starter
\item 8 grams salt
\end{enumerate}
\textbf{Instructions:}
\begin{enumerate}
\item \textbf{Prepare the Dough:} In a large mixing bowl, combine the flour and water.
Mix until you have a shaggy dough with no dry spots.
\item Add the sourdough starter and salt to the mixture. Incorporate them thoroughly
until you achieve a smooth and homogenized dough.
\item \textbf{Fermentation:} Cover the bowl with a lid or plastic wrap. Allow the dough
to rest and ferment until it has increased by at least 50\% in size.
Depending on the temperature and activity of your starter,
this can take anywhere from 4 to 24 hours.
\item \textbf{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 \textbf{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.
\item Cover the pan with a lid. This traps the steam and ensures even cooking
from the top, allowing for easier flipping later.
\item After about 5 minutes, or when the bottom of the flatbread has a
golden-brown crust, carefully flip it using a spatula.
\item \textbf{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.
\item Cook the flipped side for an additional 5 minutes or until it's also golden brown.
\item \textbf{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 \textbf{Serving Suggestion:} Enjoy your sourdough flatbreads warm,
paired with your favorite dips, spreads, or as a side to any meal.
