Which ingredient helps to stabilize egg white foams in baking?

• A. Flour
• B. Baking soda
• C. Cream of tartar
• D. Butter

Answer: (C)

The ingredient that helps to stabilize egg white foams in baking is cream of tartar. It is a type of acidic salt derived from tartaric acid, which is found in grapes. When added to egg whites before beating, cream of tartar changes the pH level of the egg whites, strengthening the protein structure. This allows for greater stability and volume when whipping the egg whites, which is essential for creating meringues, soufflés, and other baked goods that rely on airy textures.

The addition of cream of tartar helps to prevent the egg whites from collapsing, ensuring that they maintain their volume and structure throughout the baking process. This stability is crucial for achieving the desired light and fluffy results in recipes that use whipped egg whites.

Other ingredients, such as flour and baking soda, serve different purposes in baking and do not have the same stabilizing effects on egg whites. Butter, being a fat, would weigh down the mixture and hinder the formation of a stable foam when whipped with egg whites. Thus, cream of tartar is the best choice for stabilizing egg white foams in baking applications.
