What Is Cream Of Tartar?

Cream of tartar is an acidic powder that is created in the wine-making process. It comes from the tartaric acid in the grapes. Cream of tartar is considered a leavening agent because when it is mixed with baking soda, it forms carbon dioxide. This gas is what helps fluff up and allows your baked goods to rise.

You will also see cream of tartar used in recipes like meringues. In this instance, cream of tartar helps to strengthen the bubbles created when whipping egg whites. This is why meringues hold their shape so well during the baking process.

I haven’t tried this, but the cream of tartar can also be added to whipped cream to stabilize it so that it doesn’t soften and lose its shape. See below for a fun recipe to try out for your next dessert!
