Corn syrup is a sweet and thick liquid made from corn starch, primarily consisting of glucose molecules. It is commonly used as a sweetener and thickening agent in various food products, including baked goods, candies, sauces, and beverages. Corn syrup helps to prevent crystallization in candies and provides moisture and chewiness in baked goods. It is also used as a base for making caramel and as a glaze for fruits. Corn syrup comes in different varieties, including light corn syrup, which is clear and mildly sweet, and dark corn syrup, which has a richer flavor and color due to the addition of molasses.
