corn syrup

Corn syrup is a sweetener derived from corn starch through enzymatic hydrolysis, producing a liquid containing glucose and maltose. It originated in the United States in the mid-19th century and became widely used as a commercial sweetening agent. The syrup is clear, viscous, and colorless to pale yellow, with a neutral, slightly sweet taste that lacks the complex flavor profile of honey or cane sugar. Light corn syrup is filtered to remove impurities and is most common in culinary applications, while dark corn syrup contains molasses for deeper flavor and darker color. The sweetness level varies depending on processing; standard corn syrup is roughly 70-75% as sweet as sucrose by weight.

Corn syrup functions as both a sweetener and a texture modifier in baking and candy-making. It is particularly valued in pecan pies, fudge, caramels, and marshmallows, where its hygroscopic properties prevent crystallization and create smooth, glossy textures. In beverages, it serves as a bulk sweetener in sodas and syrups. Its neutral flavor makes it suitable for applications where sugar flavor would be undesirable. Corn syrup is also used in frosting, ganache, and confections where crystallization control is essential. However, it has become increasingly replaced in some applications by high-fructose corn syrup (HFCS) due to cost considerations, though this substitution is controversial in some markets.
