What Is Cornstarch Slurry?

Cornstarch slurry consists of a simple mixture of cornstarch and cold water. This combination acts as a thickening agent, ideal for sauces, soups, and gravies. When mixed with liquid, the cornstarch molecules hydrate and swell, thickening the mixture as it heats. The beauty of cornstarch slurry lies in its ability to provide a clear, glossy finish to sauces without clouding them.

Many chefs and home cooks use cornstarch slurry for its ease of use and neutral flavor. It’s gluten-free, making it suitable for a variety of dietary preferences. When thinned out with cold water, it’s easy to incorporate into hot liquids for even thickness.
