Ingredients
- 120 grams unbleached all-purpose flour
- 120 grams water (filtered or dechlorinated)
Directions
Step 1
Day 1: In a clean glass or plastic container, combine 120 grams of unbleached all-purpose flour and 120 grams of water. Mix well until you create a thick, pancake-like batter. Cover the container loosely with a lid or plastic wrap, or cover with a clean kitchen towel secured with a rubber band. Let it sit at room temperature (ideally 70-75°F or 21-24°C) for 24 hours.
Step 2
Day 2: After 24 hours, you may start to see a few bubbles forming, which indicate fermentation has started. Discard half of the mixture (about 120 grams), then add 120 grams of fresh flour and 120 grams of water. Stir thoroughly, cover loosely, and let it rest for another 24 hours at room temperature.
Step 3
Day 3: Check for bubbles and a tangy aroma. Discard half of the mixture again (about 120 grams) and repeat the feeding process with 120 grams each of flour and water. Stir, cover loosely, and let it sit for another 24 hours.
Step 4
Days 4-7: Continue feeding the starter once every 24 hours by discarding half of the mixture and adding 120 grams each of flour and water. By Day 5 or 6, the starter should be noticeably active, with more bubbles, a pleasant sour smell, and some rise and fall after feeding. If so, you can start feeding it twice daily (once every 12 hours).
Step 5
By Day 7 or later: Your sourdough starter should be fully active and ready to use when it doubles in size within 4-6 hours after feeding. At this point, you can store it in the refrigerator and feed it weekly, or continue feeding it daily if kept at room temperature, depending on how often you bake.
