<<Disclaimer: Verify this information before applying it to your situation.>> I read the posting about the Best products. Thanks. A couple of weeks ago I craved the soft frozen yogurt at COSTCO. It wasn't busy and the staff was more than happy to supply me with the name and phone number of the manufacturer of the yogurt machine mix. I called them and they assured me that the product was GF--both flavors, chocolate and vanilla. Unfortunately, I don't have anything in writing and I tossed the phone numbers after I called from the store, but you can confirm it if you go to COSTCO and ask at the snack counter. It was great to be able to snack on it again. :) Linda Scalice Long Island, NY
