Barding
This is a method of introducing fat to a very lean joint of meat to keep it moist and succulent during cooking. It also adds flavour to the meat. A layer of fat or fatty meat such as streaky bacon is wrapped around the meat to be cooked and the outer covering of fat bastes the meat during cooking, preventing it from drying out. Prepared roasting joints of rolled, meat available from Waitrose such as stuffed belly roast of pork are sold ready barded.
