Tasting Notes
Selecting and Buying
Grapes are the only significant natural source of tartaric acid, and cream of tartar is obtained from sediment produced in the process of making wine.
Preparation and Use
Cream of tartar is widely known to help stabilize and give more volume to beaten egg whites. It is the acidic ingredient in some brands of baking powder. It is also used to make a creamier texture in sugary desserts just like candy and frosting, as it inhibits the formation of crystals.
Commercially, cream of tartar is used in some soft drinks, candies, bakery products, gelatin desserts, and photography products.
In cooking, Cream of Tartar is used to give a creamier texture to icings and candy and to add volume and stability to egg whites in baking. It is also a key ingredient in baking powder, and it is often added to sodas, souffles and other baked goods.
While there is no equivalent substitute, a equal amount of lemon juice or vinegar may work. In a recipe that calls for baking soda in addition to cream of tartar, use baking powder instead of both the baking soda and cream of tartar: baking powder is 2/8 baking soda and 5/8 cream of tartar.
Conserving and Storing
Store tightly sealed in a cool, dry place for up to one year.
