About cream of tartar

Cream of tartar is an acidic powder derived from tartaric acid, a natural byproduct of winemaking. It's virtually flavourless with a slightly acidic aroma. In baking and cooking, it stabilises egg whites for meringues and soufflés, activates baking soda to create lift in cakes and biscuits, and prevents sugar crystallisation in frostings and confectionery. It's indispensable for recipes requiring precise chemical reactions.
