Question

What is baking powder

Answer 1

Baking powder is a preservative material

Answer 2

Baking powder is a blend of acid (most commonly calcium acid phosphate, sodium aluminum sulfate or cream of tartar) and alkali (sodium bicarbonate is known commonly as baking soda). By adding water to this mixture, a chemical reaction is achieved, producing carbon dioxide which is trapped in tiny air pockets in the dough or batter. Heat releases additional carbon monoxide and expands the trapped carbon dioxide gas and air to create steam. The pressure expands the trapped air pockets, thus expanding the overall food.
