answer:I would venture a guess that you saw a wok coated with ceramic inside and out. Ceramic cookware is currently very popular and and you should be about to buy one any any decent department store. I’m not a proficient oriental cook, so, although I own a TFal wok, I never use it. It’s just simpler to use a saute pan. That trick where you toss and flip a pan at the same time so that the contents come out the back and then forward an not that hard to master. To me, its the same effect as a wok.
