With the discovery of sourdough bread, a whole new subset of bakers emerged; all of whose goods were equally scrumptious. In sum, if you need a sourdough bread fix, San Francisco is your city.

To do this, he said, you basically mix a quarter of a cup of flour and water 35g flour and 60g water together and you let it sit for a day. Then you throw out all of it apart from a little bit, and you do it again. Once you have your starter, you can begin making your bread — a process that Baker says generally takes one to two days.
I actually recommend doing it all by hand, to get a feel for the process. Baking sourdough is an amazing opportunity for patience and presence, and then you get to share it with someone. Note: With each feeding, you can either discard the unused portion of starter or use it for another purpose. The starter is ready to use around hours after the last feeding.
Mix together 20g active starter, 90g whole wheat flour and 90g lukewarm water. Be sure to do this hours before you plan to mix your dough see next step. By that time, it should be nice and bubbly and look like thick pancake batter. Mix together everything except the salt and about g of the water until no dry spots remain.
Let the dough rest for 20 minutes. Keeping dough in the bowl, stretch and fold it upwards while rotating the bowl to give it strength and redistribute the yeast and warmth. Repeat two more times at to minute intervals. Let it rest for another 20 minutes before shaping the loaves see next step. Roll the dough from the top towards you and end when the seam faces you, then seal it on all sides by using the palm of your hand to press together the seam. Repeat with other piece of dough. Dust dough lightly with flour, then use a bench scraper to pick up one piece of dough keeping all the tension in the dough , and place it seam-side up inside a lightly floured basket or bowl to rest.
That's it. If you add anything else, it's not real sourdough. Eventually, the sugars in the flour start to break down, and fermentation happens on its own. Tredgold handed me a plastic spoon and pointed me to a bucket. I could see bubbles rising to the surface of the bucket -- a sure sign of microbial activity. The starter tasted like very sour yogurt to me, but Tredgold treated the experience like tasting a fine wine, smelling and savoring.
Semifreddi's produces 9, loaves of sourdough each day. But no two loaves taste exactly alike. The yeast makes the bread rise. And the bacteria create the acids that make the bread sour. The flavors vary from day to day, and batch to batch. Sourdough is one of the most ancient breads , dating back at least 5, years.
It's reasonably easy to create a starter from scratch, but tricky to master the triple arts of crust, crumb and flavor when baking. So much depends on capturing enough wild yeast to make the bread light and airy. Adding commercial yeast is not a permitted technique at the baking stage if the goal is authentic, old-fashioned sourdough. And our hands. Rose was so passionate that I decided to try growing my own sourdough starter at home more on that below.
A little voice nagged at me, though. I live in Oakland. Louise Boudin even saved the starter from a burning building in the earthquake. A museum docent told me the starter is so special and irreplaceable that the Boudin mothership sends its retail stores fresh starter every 23 days. Without it, they say the sourdough those stores produce would stop tasting like San Francisco sourdough and start tasting like San Diego or Sacramento sourdough.
Scientists identified it here in , so they named it Lactobacillus sanfranciscensis. Scientists did identify Lactobacillus sanfranciscensis here. But recent studies have found it in up to 90 percent of countries where sourdough is produced. So from a biological standpoint, San Francisco sourdough is not all that distinctive. His lab studies fermentation full time … including the microbes you find in sourdough. Science is still learning about the lactic acid bacteria like L.
Other fermented foods have lactic acids, too, like miso, yogurt and kimchi. Or how they get into your sourdough starter when you make it in your kitchen.
One explanation is that the bacteria could be in the flour to begin with. They could also be on your skin or floating around your kitchen, but Wolfe says those are less likely to become the dominant bacteria in your starter.
The Sourdough Project is soliciting hundreds of sourdough starter samples from amateur and professional bread bakers across the country. To participate in this public science project, get started by filling out this questionnaire. Scientists will analyze samples to answer the baseline question: How variable are the microbes from region to region?
