Leavening

Leavening agents generate carbon dioxide gas so that, upon cooking, doughs and batters will have air pockets that, upon heating, will yield a fluffy texture. This topic discusses the use of biological (i.e., yeast, bacteria), chemical (i.e., mixtures of acids and bases, such as baking powder, baking soda, cream of tartar, phosphates) and other leavening agents such as steam.
