This Christopher Kimball 8-inch skillet is made from 5-ply professional grade stainless steel sandwiched around a pure aluminum core that provides superior heat conductivity and cooking performance. The magnetic stainless steel exterior makes this premium cookware ideal for any cooking surface, including induction cooktops. (When rated against other top brands for induction cooking, this skillet was more efficient.) We use an 8-inch skillet for a wide range of kitchen tasks from toasting nuts and spices, to breakfast duty, to omelets, to smaller jobs such as steak for one. It’s oven safe up to 500 degrees, and the riveted stainless steel handles stay cool during stovetop cooking.
