Cream of tartar is a fine white powder derived from a crystalline acid found inside wine barrels. It is commonly added to candy and frosting mixtures to create a creamier consistency and is also used to improve the stability and volume of beaten egg whites. This ingredient helps prevent crystallization in candy making, ensuring smooth textures.

Odorless and colorless with a slight acidic taste, cream of tartar is a versatile ingredient in baking and candy preparation. It is kosher certified and gluten-free, making it suitable for a variety of dietary preferences and culinary uses.
