This is interesting, I've never heard of cassava flour before. But I have so many people in my family with gluten alergies and sensitivities, that this might be a great thing for my entire family to try. I don't know if I'll be able to buy the root where I live, but I can buy the flour pre made. But I didn't even know to look for it before. Now I do, thanks. Looking forward to some baking this weekend!
