Cream of What Now?

Cream of tartar is one of those mystery ingredients you might have seen in your grandma's pantry without knowing what it's used for.

What Is Cream of Tartar Used For?

Adding a small amount of cream of tartar when you're beating egg whites—usually 1/8 teaspoon per egg white—speeds up the creation of foam and helps stabilize the structure of those minuscule air bubbles you're whipping up. In baking, this means mile-high meringue pies, melt-in-your-mouth meringue cookies, and angel food cakes that practically float off the plate.

Why Is Cream of Tartar in Snickerdoodle Cookies?

It's what separates a tangy, chewy snickerdoodle from an ordinary cinnamon-coated sugar cookie. The acid in cream of tartar gives snickerdoodles their distinctive tangy flavor, and the chew happens because cream of tartar prevents sugar in the cookie dough from crystalizing into crunchiness. Science!
