tsp.baking powder
Baking powder is not a significant source of nutrients; it is used in small quantities (typically 1-2 teaspoons per recipe) and contributes minimal calories or macronutrients to finished baked goods.
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 such as cornstarch or potato starch. It was developed in the 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. Modern baking powder is typically formulated as "double-acting," meaning it releases gas in two stages: once when wet ingredients are combined, and again when exposed to oven heat.
Culinary Uses
Baking powder is essential in quick breads, cakes, cookies, biscuits, and pancakes where rapid leavening without fermentation is desired. It is widely used across American, British, and Australian baking traditions. The ingredient is typically mixed with dry ingredients before combining with wet components; proper incorporation and immediate baking are critical to capturing the leavening effect. Baking powder is incompatible with acidic ingredients like buttermilk or lemon juice, which can neutralize its effectiveness, though some recipes intentionally use both baking powder and baking soda to manage acidity and optimize rise.
