This 25-ounce container of McCormick Culinary Cream of Tartar is a fine white powder used to stabilize whipped egg whites, activate baking soda for leavening, prevent sugar crystallization and preserve the bright color of boiled vegetables. Packaged for commercial kitchens but useful in any well-stocked pantry, this cream of tartar arrives ready to measure and incorporate into recipes without extra preparation.

How does cream of tartar help meringues and whipped egg whites?

Cream of tartar lowers the pH of egg whites slightly, which helps proteins coagulate more uniformly and hold air when beaten. The result is firmer, glossier peaks that resist weeping during baking and cooling.

• Stabilizes foam to extend peak hold time
• Improves gloss and fine structure of meringues
• Reduces risk of liquid separation (weeping)
• Useful for soufflés, macarons and pavlovas

Can it act as a leavening agent in cakes and quick breads?

Yes—when combined with baking soda, cream of tartar produces carbon dioxide, which lightens batters and doughs. This makes it a handy component in recipes such as angel food cake or other formulas that need reliable lift without commercial baking powder.

• Pairs with baking soda to create homemade leavening
• Helps produce uniform crumb and rise in cakes
• Good for recipes that call for single-ingredient leavening control
• Ideal for large-batch or restaurant-sized preparations

What other culinary uses does McCormick Culinary Cream of Tartar have?

Beyond baking, cream of tartar is useful for controlling sugar crystallization, brightening cooked vegetables and stabilizing whipped cream or dessert sauces. Its versatility makes it a small but powerful addition to both sweet and savory kitchen tasks.

• Prevents sugar syrups from graininess when making candies
• Keeps boiled vegetables tasting fresh and looking vibrant
• Strengthens whipped cream for coffee drinks and plated desserts
• Enhances texture in cookies, brownies and specialty confections

How should I store and measure this cream of tartar for best results?

Proper storage preserves potency and prevents clumping: keep the container sealed in a cool, dry place away from heat, humidity and direct light. Always use dry measuring tools to avoid introducing moisture, which can degrade the powder and shorten shelf life.

• Store tightly closed in a cool, dry environment
• Avoid heat, humidity and direct sunlight to maintain quality
• Use dry measuring spoons and cups to prevent moisture contamination
• Guaranteed shelf life when stored properly; suited for commercial use
