On this page, corn flour refers to the fine starch powder extracted from corn, known as cornstarch in North America and maize starch in some other regions. It is commonly used as a thickening agent in sauces, gravies, soups, and custards, and can also be used in some baking recipes to soften texture. One metric cup of corn flour weighs approximately 120 grams.
