This set features a 5.25-quart round cocotte, a 3.5-quart braiser, a 10-inch grill pan, and a universal lid that can be used on each piece. Thoughtfully designed, each piece features sloped sides and attachable rubberized bumpers to accommodate its nesting abilities. Cast iron possesses exceptional heat-retaining qualities, so the pots heat evenly throughout. With a heavy weight, tight-fitting lid that retains moisture and tiny spikes on the lid interior that create a rain-forest effect evenly returning juices back onto food, you can expect perfectly cooked dishes every time.
