Clean rabbit thoroughly. Prepare the bread crumbs, onions, butter, salt, pepper and savoury for dressing and fill rabbit; sew together or fasten with skewers. Place in a roasting pan and lay four or five slices of fat pork across its back. Add a little water and cover the pan. Bake at 350°F until meat is tender (about 25 - 30 minutes per pound). Remove from oven and thicken drippings for gravy. Top with your favourite pastry and return to oven. Bake at 450°F until pastry is nicely browned. Serve immediately.
