Substitute for Cream of Tartar in Macarons: Stabilize Meringue
Cream of tartar stabilizes the whipped egg whites that form the base of macaron shells. It strengthens the meringue's protein structure, helping achieve stiff, glossy peaks that hold their shape during piping and baking.
Best Substitute
Lemon Juice
1/2 teaspoon lemon juice per 1/4 teaspoon cream of tartar
Lemon juice provides the same acidic stabilization of egg white proteins as cream of tartar. It helps the meringue reach stiff peaks and produces smooth macaron shells. The small amount does not impart a lemon flavor.
Other Options
White Vinegar
1/2 teaspoon white vinegar per 1/4 teaspoon cream of tartar
Works identically to lemon juice for stabilizing meringue. Use distilled white vinegar for a neutral flavor. The tiny amount evaporates during baking.
Baking Powder
1 teaspoon baking powder per 1/4 teaspoon cream of tartar
Only use if the recipe also calls for baking soda. Baking powder already contains cream of tartar. It will not stabilize meringue, so only works in non-meringue macaron methods.

Frequently Asked Questions
What can I use instead of cream of tartar in macarons?
Use 1/2 teaspoon of lemon juice or white vinegar per 1/4 teaspoon of cream of tartar. Both acids stabilize egg whites for stiff, glossy meringue peaks. The small amount does not affect the macaron's flavor.
Can I make macarons without cream of tartar?
Yes. Lemon juice or white vinegar provides the same acid stabilization. You can also skip it entirely if you whip the egg whites carefully, though there is a higher risk of the meringue collapsing. An acid is recommended for consistent results.
