Founded in 1925, the Le Creuset factory in Fresnoy-Le-Grand France is a world-renowned maker of enameled cast iron cookware. The rigorous process starts with molten iron being sand cast from a single mold that’s destroyed after use, explaining why no two pieces are identical. Pots, pans and accessories are then painstakingly polished and finished by hand, then sprayed with two coats of enamel and fired twice. No other procedure yields cookware that so evenly conducts and retains heat, making Le Creuset cast iron second to none for slow cooking.
