About Potassium hydrogen tartrate

Potassium hydrogen tartrate, commonly called cream of tartar, is a crystalline acidic salt that forms naturally during winemaking and is collected and purified for culinary use. It is used in baking, including to stabilize beaten egg whites and to contribute acidity in some leavening mixtures.

The food ingredient is typically a fine white powder or small crystals with a tart taste. It is sold as a dry culinary powder and is generally used in small amounts rather than eaten alone. Purity and particle size can vary, while mixtures containing other leavening ingredients are distinct products.
