As with much of what.s happening in the kitchen, cookware is being revived by the seemingly opposing forces of innovation and a return to basics. A renewed appreciation of copper pots, Dutch ovens, and other traditional standbys is taking place even as top chefs snap up ferrous pans for use with induction stoves and the latest gadgets to reduce the time and stress of kitchen prep. As a result, today’s cookware selection is chock-full of pots, pans, baking sheets, and casserole dishes that satisfy the modern kitchen’s need for form and function.
