A leavening agent often used to lighten breads, cakes and batters.
It is a mixture of sodium bicarbonate (baking soda) and an acid (such as cream of tartar- potassium bitartrate.)
It is typically made with a starch such as corn starch as well.
Baking Powder is a very fine white powder, similar in appearance to baking soda or corn starch, two ingredients that it is most commonly comprised of. The addition of water instantly catalyzes a reaction which releases carbon dioxide gas.
