Substitution for Cream of Tartar

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 entirely

As a leavening agent - replace the baking soda and the cream of tartar in the recipe with baking powder. One teaspoon of baking powder replaces 1/3 tsp of baking soda and 2/3 tsp cream of tartar

For frosting - leave the cream of tartar out. No substitute is necessary.
