Corn starch, also known as cornflour in some regions, is a fine, white powder derived from the endosperm of the corn kernel. It's virtually flavorless in its raw state but indispensable in the kitchen as a thickening agent. Its incredibly smooth texture and pure white appearance make it ideal for creating clear, glossy sauces, gravies, and desserts. When heated with liquid, corn starch granules swell and gelatinize, resulting in a thickened consistency. Chefs and home cooks frequently use corn starch to achieve the perfect texture in everything from stir-fries to puddings. It is a versatile ingredient for gluten-free baking and cooking.

Cornstarch should be stored in an airtight container in a cool, dry place away from direct sunlight. Proper storage prevents clumping and moisture absorption, which can affect its thickening properties. Under these conditions, cornstarch can maintain its quality for several years. Avoid storing it near strong-smelling foods, as it can absorb odors.
