For cast-iron or stainless steel, the answer is Le Creuset. Each piece's three-layer construction has a stainless steel interior and exterior and a heat-responsive aluminum core. The rim is rolled, sealed and polished to protect the internal aluminum layer, as well as to make for easier pouring.
Le Creuset's signature stainless steel set is an essential gift for newlyweds or for a new home. The set includes a variety of sizes: a 26 cm Fry Pan, 1.9 L Saucepan with Lid, 3.8 L Saucepan with Lid, 2.8 L Sauté Pan and 8.3 L Stockpot with Lid and Pasta Insert. Lids and inserts are counted as individual pieces.
