Light corn syrup is a clear, colorless syrup made from cornstarch that has been treated with enzymes and acids to convert its glucose molecules into fructose, resulting in a sweeter product. It is often used as a sweetener in recipes, such as in candy making, baking, and as a glaze for baked goods. Light corn syrup also acts as a thickener and helps prevent crystallization in recipes like caramel sauce and frostings. It has a mild, sweet flavor and a thick, syrupy consistency.
