tbs. baking powder
Baking powder is primarily a leavening agent and is used in small quantities; it contributes negligible calories and nutrients to finished products. However, it adds sodium to baked goods depending on the formulation and amount used.
About
Baking powder is a chemical leavening agent composed primarily of sodium bicarbonate (baking soda), an acid (typically cream of tartar or sodium aluminum sulfate), and a moisture-absorbing agent (often cornstarch). It functions by releasing carbon dioxide gas when moistened and heated, causing batters and doughs to rise and become light and airy.
Double-acting baking powder, the most common variety, contains two acidic components that provide leavening at different stages: once when wet ingredients are added to dry ingredients, and again during baking. Single-acting baking powder reacts only when heat is applied. The cornstarch component prevents clumping and moisture absorption during storage.
Culinary Uses
Baking powder is essential in quick breads, cakes, muffins, pancakes, biscuits, and cookies where a tender crumb and rapid rise are desired without yeast fermentation. It is particularly valuable in recipes requiring immediate baking, as opposed to yeast-leavened products that require rising time. In savory applications, it is used in certain batters for fried foods and dumplings to achieve lightness. Proper measurement and the freshness of the baking powder significantly affect lift and texture; old or improperly stored baking powder loses potency and yields dense results.
