The best cookware to use on gas cooktops are constructed of non-stick anodized aluminum, stainless steel, stainless steel with copper bottoms or cast iron. A good set of pots and pans can be very expensive, so matching the type of cookware to the intended use is considered important.
OnTheGas.org rates the non-stick hard anodized Anlon Advanced Cookware set as the best. Good Housekeeping prefers stainless steel or stainless steel with copper bottoms for all of its top selections, but mentions the Anlon set mention further down its list. Professional chefs consider cast iron cookware to be a precision cooking instrument and versatile because it can be used on the stove top or in the oven.
