Staub's innovative enamel coating takes cast-iron cooking to the next level with improved performance, style and durability. A heavy lid to seal in moisture paired with heat-retaining cast iron make this oven ideal for slow-cooking homemade chili or a hearty stew. Heavyweight enameled cast iron transfers and retains heat evenly. Colour selections feature multicoat enameling for a glossy, vibrantly coloured "majolique" exterior finish that resembles fine ceramics; Matte Black selection features low-gloss matte enameled finish. Interior surface is matte-black enamel that is resistant to rust, chipping and cracking and does not require additional seasoning. Traces of quartz on enameled interior provide additional heat resistance and create a textured surface for improved browning. Dozens of precisely placed bumps on the lid's interior funnel evaporated juices directly back down on top of food for moist, tender results.
