Cream of Tartar

Cream of Tartar may be mysteriously named, but it's a natural byproduct of winemaking that has great culinary and household applications. This acidic white powder is an unparalleled stabilizer for egg whites (meringue, anyone?), helps prevent crystallization in sugar candies and caramels, gives frostings a smoother, creamier texture, and can even be combined with lemon juice or vinegar to create a powerful stain remover. Plus, it's a key component for making play-dough at home!
