Chef’s Secret

An active starter should float in water; this indicates sufficient gas production for leavening. A "discard" starter can be used in recipes like pancakes or crackers.

Substitutions

Best Match

Active Dry Yeast + Flour + Water

Varies (e.g., 1 tsp yeast for 500g flour)

Provides leavening, but lacks the complex flavor and texture of sourdough.

Poolish/Biga (Pre-ferment)

1:1 (by flour weight)

A pre-ferment made with commercial yeast, offering a slightly more developed flavor than direct yeast.

Baking Soda + Acid (e.g., buttermilk)

Varies

Provides quick leavening for certain recipes (e.g., quick breads) but not suitable for traditional yeast breads.

Buying Guide

Often shared by bakers or can be purchased online. Maintain it by regular feeding of flour and water.

Flavor Pairings

Wheat flour rye flour water salt. Used in breads pancakes crackers.
