Calphalon's Premier cookware wraps a heat-responsive aluminum core with four layers of durable stainless steel. The result is a precision-performance wok that resists warping, denting and staining so the mirror-polished surface stays stunning. Fitted with handles that stays cool on any type of stovetop, the wok heats quickly and stands up to high-heat stir-frying and searing—as well as the oven, broiler and dishwasher. Build a beautifully resilient cookware collection by pairing this wok with the other Premier pieces.
