Cream of tartar is the powdered form of tartaric acid, a substance that forms at the bottom of barrels when making wine. It is added to recipes for three reasons:

  • To stabilize egg whites, when whipping them for meringue. It's the ingredient that helps meringue maintain its high peaks, even after a trip through the oven. 
  • To act as a leavening agent in cookies, pancakes and other yeast-free baked goods. Combine cream of tartar with baking soda, and you get a chemical reaction that makes your treats fluffier.
  • To prevent the sugar in frostings, icings and syrups from crystallizing. In the case of frostings and icings, this results in a creamier texture.

Cream of Tartar Substitutes

If you don't have any cream of tartar in your pantry, you can use one of these substitutes in its place:

For beating egg whites - Use an equal amount of white vinegar or lemon juice, or omit the cream of tartar from the recipe entirely

As a leavening agent - Replace the baking soda and the cream of tartar called for in the recipe with baking powder. Use one teaspoon of baking powder to replace 1/3 tsp of baking soda and 2/3 tsp of cream of tartar. Since baking powder is really just a mix of cream of tartar and baking soda, this substitution won't change your recipe at all.

For frostings and syrups - Leave the cream of tartar out. No substitution is necessary.

Keep In Mind: While these substitutions will give you good results, the finished product may still come out a bit different than you're used to. Expect subtle changes in texture and appearance. That's just the nature of a substitute.

Does Cream of Tartar Go Bad?

As long as you keep your cream of tartar in an air-tight container, away from heat sources, it should keep indefinitely. So, don't sweat it if the container in your pantry is so old you don't even remember when you bought it. Just dust it off, and put it back in service.

Other baking ingredients, like baking powder, do have a shelf life.

Here's how to tell if your baking powder is still good. For more information about the shelf life of pantry foods, refer to this handy chart.
