Cassava flour is a whole food that retains all of its fiber and can actually be used as a base (versus just filler) in all of your baked goods. Cassava is a root vegetable, similar to yams or taro. In addition to being gluten- (and grain-) free it’s also nut-free, which is great news for all people dealing with multiple allergies and/or sensitivities. While many other gluten-free flours need a lot of other ingredients—especially eggs—to achieve a good consistency, cassava flour can be used by itself. This also means that a lot of recipes using cassava can be made vegan.
