Food cooks and releases on the entire surface of the pan. The raised circles on the “Hi” area allow a fraction of the cooking surface to take all of the abuse of utensils, protecting the majority of the cooking surface on the “Low” area from abrasion. The result of this has been enhanced cooking performance and non-stick durability. Healthier Cooking: this product is dedicated to helping consumers lead a healthier lifestyle through fat-free healthy cooking. Their Non-Stick System allows for cooking with little to no oil. Dishwasher Safe: Unlike ordinary hard-anodized pans, this product features a non-stick exterior. Not only does this make cleanup a snap, but it also means that the pan also won’t stain, scratch or chip so your cookware will look beautiful for years to come.
