Cream Of Tartar
Cream of tartar is a fine white powder, that produces a creamier texture in frosting, candy, and gelatin desserts. It helps make egg whites whiter and stabalize them, which adds more volumn to meringues. Creme of tartar is especially great to stiffin cookie frosting. In baking, cream of tartar helps to activate the baking soda, resulting in a better rise of baked goods.
