Cream of tartar is used, in very small amounts, to stabilize the white of the eggs (1/8 teaspoon per egg white) that are used to make meringues, sweets, or frosting. It ensures that the product comes out creamy. It works together with baking soda as a leavening agent in cake batters. It is also used to reduce the discoloration in vegetables (just add 1 teaspoon to the water) when boiling and is also used to make a thick paste to gently clean copper cookware.

If, for some reason you don’t have it in your pantry and you need a substitute you can make use of a number of substitutes based on what you are preparing.

Here are 5 common substitutes for cream of tartar.

  1. For whipping egg whites, use about equal amounts of fresh lemon juice or white vinegar in place of 1/2 teaspoon of cream of tartar.
  2. For cookies, cakes and quick breads, use 1 teaspoon of lemon juice or white vinegar for every 1/2 teaspoon of cream of tartar.
  3. For baking, and only when the recipe also contains baking soda, use 1 1/2 teaspoons (6 grams) of baking powder for every 1 teaspoon (3.5 grams) of cream of tartar. Baking powder is made up of sodium bicarbonate and tartaric acid.
  4. For some baked recipes, use buttermilk or yogurt. A 1/4 teaspoon of cream of tartar can be substituted for 1/2 cup of buttermilk, using 1/2 cup of the recipe’s other liquid. A 1/4 teaspoon of cream of tartar can be substituted for 1/2 cup of yogurt, thinned out with milk. Adjust the other liquid in your recipe.
