Description
Create your own bubbly, active sourdough starter from scratch in just 7 days using this foolproof beginner method. With only flour and water, minimal daily effort, and built-in troubleshooting, you’ll be baking crusty loaves in no time.
Ingredients
- 60 grams (about 1/2 cup) whole wheat flour or rye flour (for first feeding only)
- Unbleached all-purpose flour (for all subsequent feedings; at least 11% protein content)
- Filtered or bottled water, room temperature
Instructions
- Day 1: In a clean glass jar, combine 60 grams (about 1/2 cup) whole wheat flour with 60 grams (about 1/4 cup) room temperature filtered water. Stir vigorously until no dry flour remains. The mixture should be thick, like pancake batter. Cover loosely with a towel or coffee filter and set in a warm spot (70-75°F). Leave it alone for 24 hours.
- Day 2: Check your starter. You might see a few tiny bubbles or a slight watery layer on top. Discard about half of the mixture (roughly 60 grams) and feed it with 60 grams unbleached all-purpose flour and 60 grams water. Stir well, mark the height with a rubber band, and cover again.
- Day 3: Your starter might look less active with smaller bubbles or a grayish liquid on top (this is normal). Discard half, feed with 60 grams flour and 60 grams water, and stir well.
- Day 4: You should see more consistent bubbles and a pleasant sour smell. Your starter might double in size within 8-12 hours after feeding. Discard half, feed again with the same 60:60 ratio, and mark your jar.
- Day 5: Your starter should be reliably doubling in size within 6-8 hours. It should look bubbly and spongy with a dome on top. The smell should be pleasantly sour. Discard half and feed again.
- Day 6: Your starter should consistently double within 4-6 hours after feeding. It should pass the ‘float test’ (drop a small spoonful into water; if it floats, it’s active). Discard half, feed, and observe.
- Day 7: Your starter should reliably double within 4-6 hours, with a pleasant sour aroma and bubbly, spongy texture. It passes the float test consistently. Feed it one last time, let it peak, and use it in your first recipe. Store remaining starter in the refrigerator, feeding once a week.
Notes
If your kitchen is cold (below 68°F), the starter may take 10-14 days. If warm (above 80°F), it may be ready in 5-6 days. Don’t skip the discard step—it keeps the microbial population balanced. Save discard for pancakes or crackers. The float test is a good indicator but not foolproof; rely more on the doubling test. If starter smells like nail polish remover, it’s hungry—feed more frequently (every 12 hours).
