Made of durable cast iron for exceptional heat retention, this panini grill and press set is ideal not only for cooking up classic paninis, but it also works great for chops, vegetables, and more. The cookware features a black matte interior that requires no seasoning and will not react to acidic foods. Oils used and created when cooking penetrate the pores of the matte enamel to create a natural, smooth, nonstick surface, which provides easy food release and quick cleanup. Oven-safe to 500 degrees F and safe for use on gas, electric, and ceramic-top ranges, the cookware comes equipped with a distinctive signature handle and a helper handle, along with a cast stainless lid knob, that make for safe, easy handling. The grill's porcelain enamel interior and exterior comes in a variety of classic colors for a beautiful presentation on virtually any dining room table. Washing the grill and press by hand is recommended for best results, and a 16-page booklet with recipes from Mario Batali's latest cookbook, Molto Italiano, is included. The cookware carries a limited lifetime warranty and its grilling surface measures 11 by 11 inches.
