Gluten Free Cooking...what Kind Of Cookware? in Coping with Celiac Disease Posted August 15, 2010 · Report to Admin I'm also partial to my Calphalon hard anodized aluminum...I bought it back in the late 90's and just scrubbed the dickens out of it with Comet when I went gluten free. I think it's now made in China. I also got rid of all my old ancient non-stick and bought a set of T-Fal for those times I really want to use non-stick cookware. I live alone so have total control in my kitchen.
