A thick, sweet syrup created by processing cornstarch with acids or enzymes. Corn syrup comes in light or dark forms. Light corn syrup has been clarified to remove all color and cloudiness; dark corn syrup, which has caramel flavor and coloring added to it, has a deeper color and stronger flavor. Because it inhibits crystallization, corn syrup is particularly popular as an ingredient in frosting, candy, jams and jellies. It's also used as a pancake syrup, either maple-flavored or plain.
