Cornflour, also known as corn starch, is a fine white powder made from the starchy part of corn kernels. It is commonly used as a thickening agent in soups, sauces, gravies, and desserts. Cornflour also adds a crisp, light texture to fried items and baked goods. This gluten-free and odorless flour dissolves easily in water and is essential in both traditional and modern kitchens.
