We recommend that you place the seasoned joint (split facing down) on a trivet over a little water and cover with foil for all but the last hour of cooking. This should keep the meat moist (this is vital!).
Allow 20 mins per pound in a fairly hot preheated oven (typically 180˚C).
Baste the joint several times during the last hour when you remove the foil to brown the skin.
You may choose to lay bacon strips over the joint before cooking.
Test with a skewer to ensure that the juices run clear and the meat is cooked in the centre of your roll.
