What is cream of tartar?
First, let’s break down just exactly what cream of tartar is and what purpose is serves. Cream of tartar forms as crystals (more glamorously known as “wine crystals) on the walls of wine barrels during the fermentation process. These crystals are then refined and crushed into the powdery substance that usually sits in your kitchen cabinet. In chemical terms, Potassium bitartrate helps stabilize egg whites, keeps sugar from crystallizing, and acts as a leavening agent for baked goods. Should you run out, replacing cream of tartar may seem daunting, but in actuality, there are a plethora of substitutes that you probably already have in your kitchen. All you need to do is figure out what purpose that sub needs to serve: to stabilize, inhibite crystallization, or leaven. So before you go harvesting your own wine diamonds, check out our list of 10 cream of tartar substitutes that are sure to save your recipe.
