100% Potassium Tartrate, a natural salt product derived from winemaking by-products.
This versatile ingredient has become a staple in baking recipes due to several great properties:
Stabilizes egg whites – adding a small amount (e.g. about ¹⁄₈ teaspoon per egg white) helps the egg whites rise faster and hold firmer.
Helps whip cream – adding a small amount reduces the amount of “slump” in the cream.
