Its innovative Tefal Thermo-Spot heat indicator makes it easy to properly pre-heat pans, which helps seal in the flavour of food. When the pattern in the center turns to a solid red spot, the pan is hot and ready to cook. The cookware’s aluminum construction heats quickly and its even-heat base distributes heat throughout for reliable cooking results. The cookware’s durable nonstick surfaces (inside and out) offer effortless food release for quick and easy cleaning.
