In this chapter, you will learn how to make free-standing wheat sourdough bread. \begin{figure}[!htb] \includegraphics[width=\textwidth]{loaf-pan-free-standing.jpg} \caption{A free-standing sourdough bread made with wheat flour} \end{figure} A free-standing sourdough bread is my favorite type of bread. It combines a great crunchy crust, superb flavor, and a soft fluffy crumb. This is the type of bread that is being inhaled by my friends and family. Unfortunately making this type of bread requires a lot more effort, patience, and technique than other types of bread. You have to perfectly balance the fermentation process. You can not ferment for too short and also not for too long. The techniques you need to learn require a bit more skill. It took me several attempts to get this right. One of the challenges I faced was that I had the wrong flour. I didn't properly know how to use my oven. When should I stop the fermentation? There is a lot of information out there. I dug through most of it and have tried almost everything. In many cases the information was wrong, in other cases, I found another valuable puzzle piece. Aggregating all this information was one of my main motivations to start the bread code. My key learning was that there there is no recipe that you can blindly follow. You will always have to adapt the recipe to your local available tools and environment. But do not worry. After reading this chapter you will know all the signs to look out for. You will be able to read your dough. You will turn into a confident hobby baker that can bake bread at home, at high altitudes, at low altitudes, in summer, in winter, at your friend's place, and even on vacation. Furthermore, you will know how to scale your production from 1 bread to 100 loaves of bread. If you ever wanted to open up a bakery, consider this knowledge to be your foundation. Mastering this process will enable you to bake amazing bread without ever buying yeast again. \section{The process} \begin{figure}[!htb] \includegraphics[width=\textwidth]{sourdough-process-overview.jpg} \caption{An overview of the whole sourdough process from start to finish} \end{figure} The whole process of making great sourdough bread starts with readying your sourdough starter. The key to mastering this process is to manage the fermentation process properly. For this, the basis is to have an active and healthy sourdough starter. Once your starter is ready you proceed to mix all the ingredients. You want to homogenize your sourdough starter properly. This way you ensure an even fermentation across your whole dough. After a short break, you will proceed and create dough strength. Kneading will create a strong gluten network. This is essential to properly trap the CO2 created during the fermentation. Once you kneaded the bulk fermentation starts. Bulk fermentation because you typically ferment multiple doughs together in one bulk. Understanding when to stop this step will take some practice. But nothing to worry about, you will learn the exact signs to look out for. Once this is completed you need to divide your large blob of dough into smaller pieces and preshape each piece. This allows you to apply more dough strength and shape more uniform loaves. The proofing stage follows where you finish the fermentation process. Depending on your time you can proof at room temperature or in the fridge. Mastering proofing will turn your good loaf into a great loaf. Lastly, you will finish the whole process by baking. You will learn different options on how to properly steam your dough. This way your dough will have a beautiful oven spring. During the second stage of the baking process, you will finish building your crust. All the steps rely on each other. You will need to get each of the steps right to make the perfect bread. \section{Readying your starter} The most crucial part of the bread-making process is your starter. The starter is what starts the fermentation in your main dough. If your starter is off, then your main dough is also going to cause trouble during the fermentation. Your starter's properties are passed on to your main dough. If your starter doesn't have a good balance of yeast to bacteria, so will your main dough. \begin{figure}[!p] \centering \includegraphics[width=\textwidth]{1-ready-starter} \caption[Readying a starter]{A flowchart showing how you can prepare your starter before baking. This assumes you are using a stiff starter.} \end{figure} Generally, think of the dough you are mixing as a big starter with salt. After mixing all the ingredients you have a green field environment again. The yeast and bacteria start to fight again to outcompete each other. There is plenty of food available and they all do their best to win. Depending on the starter you mix into your dough some of the microorganisms might have an advantage over the others. The first option to achieve a good balance is to apply feedings. If your starter hasn't been fed in a long period the bacteria dominate. This happens if your starter has been sitting unused in the fridge for instance. As more and more acidity piles up the environment is becoming more and more hostile to the yeast. The lactic acid bacteria tolerate this environment better. Your dough fermentation would be more towards the bacterial side with this starter. By applying a couple of feedings the yeast becomes more active. The older your starter the more acid resistant the yeast becomes. Initially, I had to feed my starter 2-3 times to fix the balance. With my more mature starter, one feeding seems to be enough to balance the microorganisms. Some people use a 1:1:1 ratio to refresh the starter. This would be one part of the old starter (10g for instance), 1 part of flour, and one part of water. I think this is utter rubbish. As mentioned your starter is a gigantic dough. You would never a 1:1:1 ratio to make a dough. You might use a maximum of 20 percent starter to make a dough. That's why I advocate using a 1:5:5 ratio or a 1:10:10 ratio depending on how ripe your starter is. As I almost always use a stiffer sourdough starter due to its enhanced yeast fermentation advantages (see section \ref{section:stiff-starter}) my ratio is never 1:5:5. My ratio would be 1:5:2.5 (1 part old starter, 5 parts flour, 2.5 parts water). If it is very warm where you live you could opt for the aforementioned 1:10:5 or 1:20:10. This way you slow down the ripening of your starter. You can use this trick too to make starter feeding work with your schedule. If your starter is typically ready in 6 hours but today you need it ready later, simply increase how much flour/water you feed your starter. These are all values that you need to experiment with on your own. Every starter is unique and might behave slightly differently. The second option at your disposal is the starter quantity that you use to make the dough. As previously stated your starter regrows inside of your main dough. While I would normally use 10-20 percent of starter based on the flour, sometimes I go as low as 1 percent starter. This way the microorganisms have more room to balance out while fermenting the dough. If my sourdough starter has not been fed in a day I might use 5 percent of sourdough to make a dough. If I push this to 2 days without feedings I lower the starter amount even further. I would opt for the previously mentioned 1 percent starter. If the food is very scarce your microorganisms will sporulate. They need to regrow again from the spores they created. In this hibernation state, it takes longer for them to become fully active again. I have tried several times to make dough directly out of a dry starter. I wasn't successful because the fermentation took too long. The microorganisms had to regrow from spores and then begin the fermentation. As explained earlier there is a limit to fermentation times as your dough naturally breaks down. Furthermore, you want your microorganisms to outcompete other pathogens contained in the flour. The less starter you use the easier it is for them to reproduce. A strong starter will outcompete other germs. While the method of reducing the starter works, I recommend option one more. It will reliably create better bread. Option 2 is typically what I use when I fed my starter in the morning but didn't manage to make a dough in the evening. I don't want to feed my starter again the next morning. I would like to make a dough directly without waiting and thus use less of the very ripe starter. Over time you will become more accustomed to your starter and how it behaves. You will be able to read the signs of its activity and judge its state. \section{Ingredients} This chapter is still pending and will be added soon. \section{Hydration} This chapter is still pending and will be added soon. \section{Autolyse} This chapter is still pending and will be added soon. \section{Fermentolyse} This chapter is still pending and will be added soon. \section{Dough strength} This chapter is still pending and will be added soon. \section{Controlling fermentation} This chapter is still pending and will be added soon. \section{Optional Preshaping} This chapter is still pending and will be added soon. \section{Shaping} This chapter is still pending and will be added soon. \section{Proofing} This chapter is still pending and will be added soon. \section{Scoring} This chapter is still pending and will be added soon.
