Leaveners

There are many different ways in which a baked product may be leavened. Some are leavened through the use of a technique or method, others by the addition of an ingredient, and others still by a combination of the two. (For more information on leavening, see “Leaveners” in Chapter 4.) Ingredients that are added to provide leavening fall into one of two categories, biological (yeast) or chemical (baking soda or baking powder).
