<<Disclaimer: Verify this information before applying it to your situation.>> Can someone verify that Arrow Mills Brown Rice Flour is gf? The packaging does not say wheat or gluten free...I'm not having much luck getting my bread to come out, so I'm buying a lot of rice flour - the Arrow Mills is a bit cheaper than Ener-G and is in a larger quantitiy. The only ingredient listed is brown rice, but I'm trying to be *really* sure there are no hidden ingredients not listed. Also, I'm confused about butter. I'm lactose intolerant and wonder if I'm going to have trouble with butter. I can try the soy margarines, but for convenience, would like to know about butter - especially when eating out in restaurants. Thanks....Ayn.
