Baking Soda

One of the most common leaveners in baked goods is baking soda. This simple chemical compound, also known as sodium bicarbonate, is found in nature in crystalline form but is ground into a fine powder for cooking purposes.

Baking soda can be used for a variety of things. When combined with baking powder, its slightly bitter and salty flavor acts as a leavening agent in many baked goods.
