Baking Powder

Baking powder is a solid mixture that is used as a chemical leavening agent in baked goods.

It can be composed of a number of materials, but usually contains baking soda (sodium bicarbonate, NaHCO3), cream of tartar (potassium bitartrate, C4H5KO6), and cornstarch. (A base, an acid, and a filler respectively) .

Baking powder is made by generating these solids, combining them in unique proportions, and then transferring them to packaging.

First developed in the mid 1800s, baking powder formulations have changed little since.
