A good choice, especially for heavily used cookware, is a tri-ply or five-ply combination of stainless steel and aluminum (or hard-anodized aluminum). Stainless steel provides a durable surface, providing excellent heat retention and safety. Interior layers of aluminum ensure even heat distribution. All these work together to create the ideal cooking base, whether you’re using a skillet or sauté pan.
