Cornstarch
Description
Cornstarch, also known as cornflour in some regions, is a powdery substance derived from the endosperm of the corn kernel. Renowned for its thickening properties, cornstarch is a gluten-free alternative to wheat flour, making it a popular ingredient in diverse culinary traditions. It is virtually flavorless and thus does not alter the taste of food. Cornstarch is often measured in tablespoons (Tbsp) or teaspoons (tsp) in American recipes, while European and Asian recipes may use grams (g) or milliliters (ml).
Common uses
Cornstarch is frequently employed as a thickening agent in sauces, gravies, soups, and stews. It is also used as an anti-caking agent in powdered sugar and as a tenderizing component in certain baking recipes. Additionally, it can serve as a coating for fried foods to achieve a light, crispy texture.

Cooking methods
When used in cooking, cornstarch is typically mixed with a cold liquid to form a slurry before being added to hot preparations to avoid clumping. It's also used in baking and frying as a coating or thickener.
Pairing with other ingredients
Cornstarch pairs well with both sweet and savory ingredients, enhancing the texture of dishes without impacting their flavor profiles.
