Baking Soda / Sodium Bicarbonate Measuring FAQs

Why is baking soda stronger than baking powder? ▾

Baking soda is 100% pure sodium bicarbonate, whereas baking powder is diluted with monocalcium phosphate acid salts and cornstarch filler.

How do I test if baking soda is still active? ▾

Drop 1/2 teaspoon into a tablespoon of distilled vinegar; rapid, foaming effervescence confirms strong leavening potency.
