<<Disclaimer: Verify this information before applying it to your situation.>> Several months ago when I was seeking a GF corn tortilla, I finally found one! The brand name is Garden of Eatin, Inc, Los Angeles, CA 90029. The ingredient list is: organically grown yellow corn cooked in lime water. There is no oil, salt, or yeast used in these. To be absolutely sure they were GF, I called the company direct (many months ago) and spoke with a representative (sorry, don't remember name now!). I was told these are manufactured in a entirely separate plant and they do not process them on a conveyor belt with flour at all. As to where to purchase them, I buy them from a local health food store, or your local co-ops often carry this brand. I've found the best way to heat them, it to warm them up in the fry pan. When warming in microwave they turn mushy and yucky! Hope this helps those of you looking for corn tortillas!! Diana Iowa
