Understanding their distinct characteristics is crucial for home cooks and professional chefs alike. This comprehensive guide will delve into the realm of potato flour vs cornstarch, exploring their differences, similarities, and ideal applications.

Understanding Potato Flour

Potato flour, also known as potato starch, is a gluten-free flour made from dehydrated potatoes. It’s a fine, white powder with a neutral flavor and a slightly earthy aroma. Potato flour absorbs more liquid than other flours, making it an excellent thickening agent for sauces, gravies, and soups. It also adds a tender texture to baked goods.

Unveiling Cornstarch

Cornstarch, derived from corn kernels, is another gluten-free starch. It’s a fine, white powder with a neutral flavor and a slightly grainy texture. Cornstarch is primarily used as a thickener in sauces, gravies, and glazes. It also acts as an anti-caking agent in powdered sugar and prevents sauces from separating.
