Chef’s Secret
Maintain your starter by feeding it regularly at room temperature or refrigerating it between uses to slow down activity.
Substitutions
Best Match
Commercial Dry Yeast
1 tsp per 500g flour
For quick leavening, but lacks the complex flavor of sourdough.
Baking Powder
1-2 tsp per cup flour
Chemical leavening, for quick breads; no fermented flavor.
Biga/Poolish (Preferment)
1:1Similar concept of pre-fermented dough, but uses commercial yeast.
Buttermilk + Baking Soda
1:1 (acid + base)
For quick bread recipes that rely on an acid for leavening, but no yeast.
Buying Guide
A healthy starter should smell pleasant, tangy, and consistently rise and fall after feeding.
