Cream of tartar

Cream of tartar is a fine, white powder derived from the natural tartaric acid found in grape skins, making it a byproduct of wine production. It has a mild, slightly tart flavor and a powdery texture, often used as a stabilizer in baking to prevent sugar from crystallizing and to help whipped egg whites achieve their firm peaks. In international cuisines, it is commonly employed in recipes such as meringues, soufflés, and certain cookies, enhancing volume and stability. Historically, cream of tartar has played a vital role in baking traditions across Europe and North America, dating back centuries as a key ingredient for ensuring the success of delicate desserts.
