Place ribs in large pan; pour two-thirds of the marinade over ribs (reserve remaining marinade for basting). Marinate ribs at least 2 hours. Remove from marinade; season with sambal and salt. Grill over hot grill 2-3 minutes on each side. Move ribs to cooler part of grill and cook slowly, basting with reserved marinade every 30 minutes, about 2 hours or until meat pulls away from the bone.
