<<Disclaimer: Verify this information before applying it to your situation.>> Just as a point of interest and not a recommendation, achiote is sometimes used as a food coloring (maybe a substitute for saffron?) in Mexican cooking. Personally I have never had any problem with it. I buy little seed pods in Mexican grocery stores and grind them up. They are a little bigger than whole black pepper. It has a beautiful yellow color. I do this so rarely that I can't say I have much experience with it. I always wondered why it was on the no-no lists because it has nothing to do with wheat, as far as I know. Christina Oldenburg
