Preheat oven to 350°F (180°C). Place water and vegetables in large shallow baking pan. Add ribs and cover with foil. Bake for 45-60 minutes or until meat just starts to pull away from bone. Remove from oven and cool. Discard vegetables. In a medium bowl combine Harissa honey and ketchup. Toss ribs in mixture. For extra flavour cover and refrigerate 4 hours or overnight. On a medium heat grill cook ribs until internal temperature reaches 160°F (71°C). Use a brush to apply remaining sauce.
