Baking Powder

Baking powder is a common leavening agent used in baking to make dough and batter rise. It contains a mix of an acid (like cream of tartar) and a base (usually baking soda), along with a moisture-absorbing ingredient like cornstarch. When baking powder is mixed with liquid and heated, it produces carbon dioxide gas, which forms bubbles. These bubbles help create a light and fluffy texture in baked goods like cakes, muffins, and bread. There are two types: single-acting (reacts when wet) and double-acting (reacts both when wet and when heated).
