What is Cornstarch?

Cornstarch is a fine powder derived from the starchy part of corn kernels, known as the endosperm. The endosperm provides the energy for the seedling to grow into a new plant. Since cornstarch is made solely from the endosperm, it is naturally gluten-free and contains no protein.

Cornstarch vs. Flour

Cornstarch comes from the endosperm of corn kernels, while flour can be made from a variety of grains, including corn. All-purpose flour, typically made from wheat, contains gluten and is commonly used in baking. Both flour and cornstarch serve as thickening agents for sauces and other recipes.

Both flour and cornstarch can be used to fry foods, but cornstarch creates a crispier coating, especially for fried chicken, due to its higher starch content and ability to absorb moisture. Flour, on the other hand, has less starch and contains gluten. While both are common in baking, flour is the primary ingredient in breads, cakes, and cookies, while cornstarch plays a supporting role.

Cornstarch is a versatile ingredient that can work wonders in a variety of dishes, from making cookies with chewy centers to preparing the crispiest fried chicken. It adds an airy lightness to omelets and can even be mixed with all-purpose flour to create a quick homemade cake flour. Additionally, cornstarch can serve as an egg replacement in some baked goods.

How to Cook with Cornstarch

Cornstarch has double the thickening power of flour, so adjust accordingly when a recipe calls for flour to thicken sauces, soups, or gravies. To avoid clumping, first create a slurry by mixing cornstarch with a small amount of cold water, then gradually stir it into the hot liquid until fully incorporated.

How to Store Cornstarch

Cornstarch is typically used in small quantities, so proper storage is essential to preserve its freshness. There's nothing worse than opening a trusted baking staple, only to find it's no longer usable. To extend its shelf life, transfer cornstarch into an airtight container after opening. Alternatively, if left in its original packaging, ensure it is tightly sealed and stored in a cool, dry place.
