What is the primary function of cream of tartar in baking?

• A. To leaven baked goods
• B. To provide flavor to desserts
• C. To stabilize egg white foams
• D. To enhance the color of the cake

Answer: (C)

The primary function of cream of tartar in baking is to stabilize egg white foams. When egg whites are whipped, they are incorporated with air to create a foam structure that increases in volume and can be used in various recipes, such as meringues or soufflés. Cream of tartar, being an acid, helps to stabilize this foam by increasing the stability of the protein structures. This prevents the air bubbles from collapsing, yielding a firmer and more voluminous result.

In addition to this stabilizing effect, cream of tartar can also promote the formation of a finer texture in the foam, which is particularly important in light and airy baked goods. This characteristic is essential in achieving successful meringue peaks or ensuring that delicate pastries maintain their structure.

While leavening, providing flavor, and enhancing color may have their own respective roles in baking, they are not the primary functions of cream of tartar. Leavening agents such as baking soda or baking powder are responsible for creating the rise, flavoring is typically achieved through ingredients like vanilla or chocolate, and color enhancement would usually come from other additives or baking techniques.
