One of the easiest things to make gluten-free is a white sauce. It’s the same process to make a white sauce from rice flour as it is from wheat flour: it’s a kind of a wheat eater parity sort of food.
White sauces are basic to cooking; they usually have other things added, like garlic or melted cheese. They’re used in, well, wait a second….Google says white sauces are used in pizza, pasta, fish tacos, and a “standard Bechamel” sauce–which…still Googling…Wikipedia says is, “one of the mother sauces of French cuisine.” For my purposes, though, it’s a base for fish dishes like Fisherman’s Pie, and cheese sauce. Mmmm…cheese.
