A roasting tin is a large deep piece of cookware for roasting large cuts of meat or entire pieces of poultry in an oven sometimes with vegetables in the same pan, they are also known as a roasting tray. Some very large, very heavy roasting pans also come with side handles to aid lifting from an oven.
In addition to a roasting tin sometimes a roasting rack is used in conjunction, the rack serves to keep the meat or poultry elevated from the base of the roasting pan and therefore also elevated above the juices. A roasting tin is often quite deep not only so that large cuts of meat can be cooked but also because some people prefer to cook the meat on top of a bed of vegetables so that they absorb all the juices from the meat. We also stock a roasting tray with a built in filter for straining off the fat and juices for use in stock and in gravy.
