Cornstarch Guide: Uses, Substitutes & Cooking Tips

CORNSTARCH

Cornstarch is a fine white starch extracted from corn and widely used in Italian cooking and baking for its thickening and lightening properties. Known in Italy as amido di mais, it is especially useful in creams, puddings, sauces, cakes, cookies, and delicate desserts, where it helps create smooth textures and tender crumbs. Because it contains no gluten, cornstarch is also often combined with wheat flour to make baked goods softer and more delicate.
