Remove your stuffing from the packaging and place into a large bowl. Wrap in a sheet of buttered tin foil, rolled into a shape that resembles a Christmas cracker, and roast alongside your roasting joint. Check the stuffing is thoroughly cooked by piercing with a fork - the juices should run clear. Alternatively, check the core temperature using a meat thermometer, which should be a minimum of 72°C. Simply unwrap when done, brush with a little reduced meat stock and slice into thick slices
