Cream of Tartar

Stabilizes meringues and prevents grainy frostings for your go-to baking essential.

What it is

Cream of tartar is a natural acidic powder that forms inside wine barrels during fermentation. It's refined into a fine white powder that acts as a stabilizing agent in baking.

Flavor and texture

Tasteless and odorless with a very fine, powdery texture similar to cornstarch

Best uses

Essential for meringues, macarons, and angel food cake; stabilizes whipped cream and egg whites; prevents sugar from crystallizing in candy making; acts as a leavening agent when combined with baking soda

Storage & freshness

Store in an airtight container in a cool, dry pantry.

Cooking tip

Use 1/8 teaspoon per egg white when whipping to create stable, glossy peaks that won't deflate
