Kareng, Thanks for that info.! I hadn't realized they were labeled gluten free. I will stock up at Costco =). I have good luck with so much luck at Trader Joe's (waffles, bread, etc.) that I was worried it might be corn in general.
Cyclinglady, that was always my thinking. That if you buy the exclusively Mexican brands they wouldn't have much reason to CC.
Hopefully we don't have to cut this one. We love tortillas.
