The Lid is used with the smaller Adventure Skottle Grill to steam vegetables, speed up cooking, keep food warm etc. The lid is made of Stainless Steel with a clever pop-up knob. The lid knob can be popped up for use and collapsed for storage. Since there are no holes in the lid; the lid can be used as a prep and serving bowl. The usable area is 9 inches wide by 3 inches deep.
