Cream of Tartar Powder 1 lb: K

This is Frontier's nitrogen-flushed double wall silverfoil pack. Some Frontier packs are double wall wax-lined paper. 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. Chemically it is potassium hydrogen tartrate, the acidic potassium salt of tartaric acid, a fine white powder derived from a crystalline acid deposited on the inside of wine barrels.
