Staub is a premium French enameled cast iron cookware and bakeware manufacturer that was originally headquartered in Turckheim, Alsace, France. The first piece, a cocotte or coquelle (Dutch oven), was designed by Francis Staub in 1974 in a dormant artillery factory. Pieces are manufactured with cast iron covered with double-glazed enamel. The enamel coating makes the cookware rustproof, and easy to clean. Staub's cocottes have nubs on the interior of the lids, which enables condensation to collect and drip down to baste foods uniformly as they are cooking.
