The Calphalon Signature Nonstick 12-in. Flat-Bottom Wok with Cover is made with a Sear Nonstick cooking surface that evenly sears, browns, sautés and seals in juices when cooking meats, seafood and vegetables. This wok pan is so durable that you can cook with metal spatulas, spoons and whisks, and is dishwasher safe for easy cleanup. Now, you can have it all − a metal utensil-safe non stick pan that sears just like stainless. Traditionally shaped with high, sloped sides for tossing foods, this cooking wok has a flat bottom for easy stir-frying on modern stovetops, and is finished with beautiful brushed stainless steel handles.
