How baking soda works in recipes
When baking soda meets an acidic ingredient, it releases gas quickly. That gas creates lift, while the alkaline environment can also speed browning and affect flavor.
What Is Baking Soda?
Baking soda is sodium bicarbonate, an alkaline leavener used in many cookies, quick breads, and cakes. It reacts quickly when combined with acid and moisture, producing carbon dioxide gas that helps batters rise.
When to choose baking soda
Choose baking soda when your recipe has acidic ingredients like yogurt, buttermilk, cocoa, honey, or lemon juice. It is especially common in cookies and quick breads.
Common mistakes
Too much baking soda can leave a soapy taste and uneven rise. If your recipe does not include enough acid, the reaction can be incomplete.
FAQ
Is baking soda the same as bicarbonate of soda?
Yes. They are different names for the same ingredient: sodium bicarbonate.
Can baking soda replace baking powder 1:1?
No. Baking soda is stronger and needs acid, so direct 1:1 swaps usually fail.
Why does baking soda improve browning?
It raises pH, which can speed browning reactions in many batters and doughs.
