This exciting hybrid combines qualities of both traditional metal and non-stick cooking surfaces. Now not only can you brown, sear, and reduce sauces as the recipe intended, but you can also breathe a sigh of relief as you won't have a battle removing food and stains from the pan following use. How did this happen you ask? CALPHALON ONE INFUSED ANODIZED is manufactured with a revolutionary anodization process. Both interior and exterior surfaces are infused with an advanced release polymer which actually penetrates below the surface of the metal, into its very pores, offering superb durability and versatility. The intrinsic properties of aluminum ensure fast and even heating, as you've come to expect from Calphalon. On the large size, this sauce pan is handy for cooking vegetables and grains, as well as smallish amounts of soups and chowders.
