cream of tartar
A fine white powder derived from a crystalline acid deposited on the inside of wine barrels. Cream of tartar is added to candy and frosting mixtures for a creamier consistency, and to egg whites before beating to improve stability and volume. It's also used as the acid ingredient in some baking powders.
