Whisk honey, hoisin sauce, soy sauce, tahini, green onion, sherry, garlic, chili sauce and orange extract in a medium bowl. Place spareribs in a glass or stainless steel bowl and pour marinade over the top. Toss until evenly coated. Refrigerate for 4 to 6 hours, turning several times.
Preheat oven to 325° F.
Drain ribs, reserving marinade. Place ribs on a rack in a shallow roasting pan. Bake for 45 minutes, basting every 15 minutes. Discard marinade at this point. Raise oven temperature to 325° F and bake for 15 more minutes, or until tender and dark golden brown. Serve warm.
