What each ingredient does
- Cream of tartar
- Provides acidity that reacts with baking soda to release gas for rising.
- Baking soda
- Supplies the alkaline base that reacts with the acid to produce carbon dioxide for lift.
The step that matters
Mix thoroughly and sift several times. Baking soda and cream of tartar must be evenly distributed, or some spots will have too much acid or base, causing uneven rising and bitter or soapy patches in baked goods.
