Cream of Tartar (potassium bitarate) is added to beaten egg whites to improve their stability when whipped for making meringues, soufflés and angel food cakes. Who doesn t need a little more stability in their life?!?

It also prevents cooked sugar from crystallizing, making it good for adding to candies and frostings to ensure a creamy texture. It’s a must-have ingredient for snickerdoodle cookies.
