The Calphalon Unison Nonstick 4 quart saute pan is perfect for sauteing large dishes as well as browning and searing. Unlike other nonstick, Calphalon's "sear" nonstick cooking surface lets you sear and brown foods almost as well as you could in a stainless steel pan. It's also great for cooking sauteed dishes with tomatoes and similar ingredients because the nonstick surface will never react with foods and change their flavor. The hard-anodized aluminum construction makes this pan heat evenly and it's safe for the dishwasher, too! Pan made in the USA!
