Preheat oven to gas mark 4, 180°C, 350°F.
Place lamb chops in a large ovenproof roasting pan.
Mix together the fruit juice, ketchups, mustard and 5 spice. Pour over the chops, turn chops over to thoroughly coat.
Place in oven and cook for 20 minutes until edges of fat are starting to catch.
After 20 minutes remove from oven and carefully pour off the sauce, reserve in a separate jug.
Replace chops back in the oven for a further 5 minutes to become more sticky and golden.
Serve with BBQ sauce, baked potatoes and corn on the cob.
