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.
