˝-two tsp baking powder

Baking powder is a chemical leavening agent composed of a base (typically sodium bicarbonate), one or more acids (commonly cream of tartar and/or aluminum sulfate), and a moisture-absorbing agent (usually cornstarch or rice starch). It was developed in the mid-19th century as a more convenient alternative to yeast and produces carbon dioxide gas when activated by moisture and heat, causing batters and doughs to rise. Double-acting baking powder, the most common commercial formulation, contains two acid components that release gas at different stages—initially when mixed with liquid at room temperature, and again when exposed to oven heat—providing more reliable and consistent leavening throughout the baking process.

Baking powder is essential in quick breads, cakes, muffins, biscuits, pancakes, and cookies where rapid leavening is required without relying on fermentation. It is typically combined with other dry ingredients (flour, salt, sugar) and then mixed with wet components (eggs, milk, oil) to create uniform distribution before baking. The ingredient is used across numerous cuisines for both sweet and savory applications, from American-style pancakes to British scones to Asian baked goods. Proper measurement is critical; too much baking powder results in a bitter aftertaste and coarse crumb, while too little produces dense, flat products.
