Sourdough Starter

Making sourdough starter takes about 5 days. Each day you “feed” the starter with equal amounts of fresh flour and water. As the wild yeast grows stronger, the starter will become more frothy and sour-smelling. On average, this process takes about 5 days, but it can take longer depending on the conditions in your kitchen. As long as you see bubbles and signs of yeast activity, continue feeding it regularly.

1. Weigh the flour and water, and combine them in a 2-quart glass or plastic container (not metal). Stir vigorously until combined into a smooth batter. It will look like a sticky, thick dough. Scrape down the sides and loosely cover the container with plastic wrap or a clean kitchen towel secured with a rubber band.
2. Place the container somewhere with a consistent room temperature of 70°F to 75°F (like the top of the refrigerator) and let sit for 24 hours.
3. Continue for 4 days

If you're taking a break from baking, but want to keep your starter, you can do two things:

1. Make a Thick Starter: Feed your starter double the amount of flour to make a thicker dough-like starter. This thicker batter will maintain the yeast better over long periods of inactivity in the fridge.
2. Dry the Starter: Smear your starter on a Silpat and let it dry. Once completely dry, break it into flakes and store it in an airtight container. Dried sourdough can be stored for months. To re-start it, dissolve 1/4 cup of the flakes in 4 ounces of water, and stir in 4 ounces of flour. Continue feeding the starter until it is active again.
