Cornstarch , also known as corn flour in some regions, is a fine, white powder derived from the endosperm of the corn kernel. It's virtually flavorless and odorless, making it a versatile thickening agent in cooking. When mixed with cold water, it creates a slurry that, when heated, rapidly thickens sauces, gravies, soups, and desserts. The resulting texture is smooth and translucent, unlike flour-based thickeners, which can be cloudy. Cornstarch is also frequently used in baking to create a tender crumb in cakes and cookies, and it can prevent gluten development in bread. It’s essential to mix cornstarch with cold liquid before adding it to hot liquids to avoid clumping.

Cornstarch should be stored in an airtight container in a cool, dry place away from direct sunlight and moisture. A pantry or cupboard is ideal. Properly stored cornstarch can last for several years. Ensure the container is sealed tightly after each use to prevent clumping and maintain its thickening properties. Avoid storing near strong-smelling foods, as it can absorb odors.
