I am just wondering at what stage can we use soy flour? I was thinking it was legal since tofu is legal but I am having trouble finding info on it. Does anyone know? I made some pumpkin flax cookies (from my own recipe) last night and ended up adding a little soy flour to balance everything out, I'll be freezing most of them because 1-2 cookies and my belly is full! I decided to make them since school starts monday and they will be a grab and go snack for school days.
