Chef's Choice Classic cookware is triple ply, with two layers of 18/10 stainless steel surrounding an aluminum inner core. The resulting even heat distribution cooks your sauces and soups thoroughly--there are no "hot spots" or other flaws. In addition, the stockpot's stainless-steel handles stay cool on the stovetop, while the pot's tapered edges deliver drip-free pouring. To prevent flavor from leaking out the top, Chef's Choice Classic cookware features tight-fitting lids, which seal moisture and nutrients while cooking. The flavorful results speak for themselves. The stockpot is oven-safe to 550 degrees F and comes with a lifetime warranty. --Rivers Janssen
