How to rehydrate sourdough starter:

To use your dehydrated sourdough starter, simply rehydrate it by mixing it with water and flour. Here’s a basic guide:

  1. (Evening) In a clean jar, add dehydrated sourdough starter powder (about 10-15 grams), 3 tbsp flour, and 2 tbsp water. Mix well to create a thick batter.
  2. Loosely cover the jar with plastic wrap. Place a rubber band where the dough is starting to see the progress. Let the mixture sit at room temperature (around 70-75°F or 21-24°C) overnight. During this time, the yeast and bacteria present in the sourdough starter will begin to reactivate and multiply. 
  3. (Morning) Your starter should start showing signs of fermentation, such as bubbles and a slightly sour smell. stirring until well combined. Feed it again 3 tbsp flour and 2 tbsp water, stir well. Cover with plastic and let it sit on your counter until the evening.
  4. Repeat this process every morning and evening until your starter is consistently active and doubles in size within 6-8 hours after feeding. (About 5 days) Rehydrating sourdough starter.
