Is alum powder the same as baking powder?

No, alum powder and baking powder are not the same. While both are white powders that are used in cooking and baking, they serve different purposes and have different chemical compositions.

Alum powder

Alum powder is a type of mineral salt, specifically potassium aluminum sulfate. It is primarily used as a leavening agent in some traditional recipes, such as angel food cake. It works by reacting with baking soda to release carbon dioxide gas, which causes the batter or dough to rise. However, due to its metallic taste and potential health concerns, alum powder is not commonly used in modern baking.

Baking powder

Baking powder is a leavening agent that is composed of a mixture of baking soda, an acid (usually cream of tartar or monocalcium phosphate), and a drying agent (usually cornstarch). When baking powder is mixed with liquid and heated, the acid reacts with the baking soda to release carbon dioxide gas, causing the batter or dough to rise. Baking powder is commonly used in various baked goods, including cakes, cookies, muffins, and breads.

In summary, alum powder and baking powder are distinct ingredients with different compositions and uses. Alum powder is a mineral salt used as a traditional leavening agent, while baking powder is a more commonly used leavening agent that consists of a blend of baking soda, acid, and drying agent.
