I've decided, I'm not even going to bother contacting Arrowhead Mills. It sounds like a waste of time and energy. I'll look into Ms. Robens & Cherrybrook, though.
I actually already have a new coffee bean grinder for the purpose of grinding flour for my son! Problem was, I was trying to find stuff safe enough to grind in the thing. I already have Lundenberg brown rice,too, so that works out great! Tonight, I tested it out and made some rice flour. I mixed the flour with water, banana, and baking powder (gluten and nut free according to the label) and made pancakes. The boy loved them. He would have eaten the whole batch, but I wanted to hold back and see how his system handled them first. Hopefully, the kid isn't allergic to corn!
Considering my son broke out in hives immediately after touching milk (and scored 5 out of 6 on the RAST blood test), I don't want to try the ghee at the moment. We'll have to figure out something else.
The oil thing is something that's bothering me. My son seemed to react to some food I had cooked in canola oil, awhile back, and I realized it could be cross contaminated. Right now, I'm using a generic olive oil for everything which seems ok. I'm just at a loss as to how to cook without dairy or soy butter and without vegetable oils. Another thing that makes me nervous is spices. I've started an herb garden this spring, but it will take awhile for things to grow in. Are there completely safe spice sources out there?
Thanks for all the help so far
