Fluffy & Bubbly Sourdough Starter Recipe

4.6 from 87 reviews

A simple and classic sourdough starter recipe to cultivate wild yeast for baking delicious sourdough bread. This starter requires only flour and water and is fed daily until it becomes bubbly and active, ready to leaven bread naturally.

Ingredients

Scale

Ingredients

  • 100 grams (about 3/4 cup) all-purpose flour or bread flour
  • 100 milliliters (about 1/2 cup) lukewarm water

Instructions

  1. Mix Ingredients: In a clean jar or bowl, combine the flour and lukewarm water. Stir thoroughly until a smooth, thick batter forms without lumps.
  2. Initial Rest: Cover the container loosely with a cloth or plastic wrap and let it sit at room temperature (around 70°F or 21°C) for 24 hours to allow wild yeast and bacteria from the environment to start fermenting.
  3. Daily Feeding: Each day, discard half of the starter mixture and feed the remaining starter with equal parts flour and water by weight (about 100 grams flour and 100 milliliters water). Mix well, cover loosely, and let rest again at room temperature.
  4. Wait for Bubbles: Continue the daily feeding process for about 5 to 7 days until the starter has a pleasant sour aroma and becomes bubbly and active, doubling in size within 6 to 8 hours of feeding.
  5. Ready to Use: Once bubbly and fermented, the starter can be used in sourdough bread recipes or stored in the refrigerator for slower fermentation, feeding it weekly to maintain it.

Notes

  • Use unchlorinated water to avoid inhibiting natural yeast growth.
  • Whole wheat or rye flour can be used to jump-start fermentation due to higher nutrient content.
  • Maintain a consistent room temperature for best fermentation results.
  • If mold or off smells develop, discard the starter and start again.
