One advantage boiling has over straight grilling is cooking time. With a 45-minute to one-hour boil first, the spareribs will tenderize in the boil and need only go onto the grill to sear and caramelize on their exterior-- a process that only takes about 10 to 15 minutes, per side, over a medium-hot grill.
Preheat an outdoor grill for high heat. Remove the ribs from the oven, and let stand 10 minutes. Remove the racks from the foil, and place on the grill. Grill the ribs for 3 to 4 minutes on each side. Brush sauce on the ribs while they're grilling, just before you serve them (adding it too early will burn it).
