If you prepare a marinade pour it over spareribs, cover them, and refrigerate for at least 4 hours or until next day.
Lift ribs from marinade and drain briefly (reserve marinade).
Arrange ribs, fat-side-up, in a shallow roasting pan.
Cook, uncovered, in a 350° oven for 1 hour and 15 minutes, basting occasionally with reserved marinade.
Drain off excess fat.
When ready to barbecue, place ribs on lightly greased grill 4 to 6 inches above a solid bed of low-glowing coals.
Cook, basting with reserved marinade or with a baste and turning ribs frequently, for 15 to 20 minutes or until crisp and well browned all over.
