With aluminum cores enclosed by stainless-steel layers, Calphalon"s Tri-Ply pots and pans deliver the best attributes of both metals. The aluminum cores conduct heat quickly and uniformly across the pots and pans" bottoms and all the way up their sides. The durable, 18/10 stainless-steel interiors and exteriors are easy to clean, resist scratching, denting, warping, and corrosion, and are nonreactive to acidic food. This 3-quart sauté pan has a domed, glass lid so cooking can be monitored without releasing heat. The lid is oven-safe to 450 degrees F, ensuring the pan not only can be used atop a stove for cooking chicken and simmering asparagus but can go into the oven for braising. Handles stay cool on the stovetop and the pan"s rim is flared to facilitate dripless pouring. Tri-Ply cookware is polished to a mirror finish outside for beauty and wears a satin finish inside to conceal inevitable utensil marks. It goes safely into the dishwasher, although hand washing better preserves the mirror finish, and carries a lifetime warranty against defects. --Fred Brack
