Potato starch is a fine, white powder extracted from potatoes, primarily used as a thickening agent in cooking and baking. It's virtually flavorless, which makes it ideal for recipes where you don't want to alter the overall taste. Potato starch provides a smooth, glossy texture to sauces, gravies, and soups. As a gluten-free option, potato starch is a common substitute for wheat flour and cornstarch in many applications. It is prized for its strong thickening power and ability to create a light and airy texture in baked goods. Because potato starch gelatinizes at a lower temperature compared to other starches, it creates a translucent finished product.

Potato starch should be stored in an airtight container in a cool, dry, and dark place. This helps prevent moisture absorption and clumping. Properly stored, it can last for several years. Avoid storing it near strong-smelling foods, as it can absorb odors. Do not refrigerate or freeze, as this can cause condensation and affect its texture.
