The Battle Of The Flours: Can Oat Flour Replace Cornstarch?

Cornstarch is a common thickening agent used in various culinary applications. However, for those with gluten sensitivities or celiac disease, cornstarch can be problematic. Oat flour, a gluten-free alternative, has emerged as a potential replacement for cornstarch.
