baking powder
B1Neutral to Informal (primarily domestic/culinary contexts)
Definition
Meaning
A dry chemical leavening agent used in baking to make dough or batter rise, typically containing sodium bicarbonate (baking soda), an acid salt (like cream of tartar), and a starch.
A common household ingredient essential for creating light, airy textures in baked goods like cakes, muffins, and scones. It reacts with moisture and heat to produce carbon dioxide gas.
Linguistics
Semantic Notes
Not to be confused with 'baking soda' (sodium bicarbonate alone) or 'yeast' (a biological leavening agent). It is a pre-mixed, 'double-acting' agent in modern formulations.

FAQ
Frequently Asked Questions
Baking soda (sodium bicarbonate) needs an acid (like lemon juice or buttermilk) to react. Baking powder contains both soda and an acid, so it can work with just moisture and heat.
Not directly. You typically need about 3x the amount of baking powder to replace baking soda, and you must account for the extra acid in the powder, which may alter taste.
Mix a teaspoon with hot water. If it fizzes vigorously, it's active. If not, it's expired and should be replaced.
Some baking powders use sodium aluminium sulfate as the acid. 'Aluminium-free' versions use alternatives like cream of tartar, which some people prefer to avoid a metallic aftertaste.
