Description

This sourdough starter recipe cultivates a natural wild yeast culture using simple ingredients — flour and water. Over 5 to 7 days of regular feeding and fermentation, it develops bubbles and a tangy aroma, becoming an essential base for baking homemade sourdough bread and other fermented baked goods.


Ingredients

Scale

Starter Ingredients

  • 1 cup all-purpose flour
  • 1/2 cup lukewarm water
  • Additional for feeding: 1/2 cup all-purpose flour
  • Additional for feeding: 1/4 cup lukewarm water


Instructions

  1. Mix Flour and Water: Combine 1 cup of all-purpose flour with 1/2 cup of lukewarm water in a clean glass or plastic container. Stir thoroughly to eliminate lumps, creating a smooth batter-like consistency.
  2. Cover and Rest: Cover the container loosely with a clean kitchen towel or plastic wrap to allow airflow while preventing contaminants, and place it in a warm, draft-free spot away from direct sunlight.
  3. Allow Fermentation: Let the mixture sit undisturbed at room temperature for 24 hours. Around this time, you should start seeing bubbles forming on the surface, indicating the beginning of natural fermentation.
  4. Discard and Feed: After 24 hours, discard half of the mixture to balance acidity and yeast population. Then feed the remaining starter by adding 1/2 cup of flour and 1/4 cup of lukewarm water. Stir well to integrate.
  5. Repeat Feeding Routine: Cover again and let rest at room temperature for another 24 hours. Continue this daily routine of discarding half and feeding until the starter becomes bubbly, active, and has a pleasant tangy aroma. This process typically takes 5 to 7 days.

Notes

  • Use lukewarm water (about 75°F/24°C) to encourage yeast growth without killing it.
  • Maintain a warm environment around 70-75°F (21-24°C) for optimal fermentation.
  • Discarding half the starter daily avoids excessive buildup and maintains a balanced microbial community.
  • If mold or an unpleasant smell develops, discard the starter and restart.
  • The starter can be stored in the refrigerator once active and fed weekly to maintain its activity.
