The ribbed surface of the cast iron panini press is finished with a matte black enamel that eliminates the need for the traditional seasoning and maintenance of raw cast iron. Heat first on the stovetop or oven, then place on top of sandwiches for toasted perfection. Le Creuset produced the first enameled cast iron cookware nearly a century ago, and the original foundry still operates today, where 15 skilled artisans hand-inspect each piece. This tradition of the finest culinary craftsmanship, combined with the latest innovations in comfort and functionality, makes Le Creuset unsurpassed in both beauty and quality. While the cast iron panini press is compatible with most heating elements, it is not recommended for use on glass or ceramic stovetops.
