What Is Cream Of Tartar?
Did you know that cream of tartar is actually a byproduct of making wine? It is an acid compound called potassium hydrogen tartrate that occurs naturally during the fermentation process. What’s more, the main use of this acidic compound is in baking powder. It is also a leavening agent on its own, but only when combined with baking soda in the oven. Cream of tartar is also used to stabilize things like whipped egg whites.
