2. The part of a cooker that is used for this type of cooking.
Grill pan
An oblong metal tray with deep sides and a handle, designed to fit under the grill element in a cooker and to hold food that is being grilled, it should be solid enough so that is does not warp under very high temperatures.
Grill rack
A metal grid that fits in a grill pan. A grill rack can be used to cook food that gives off juices or fat during cooking, eg place the chops on the grill rack and cook under a preheated grill, allowing any excess fat to drain off.
