For sauce, mix all ingredients except ribs.
Rub ribs on both sides with salt and pepper.
Place ribs, bone side down, on grill over slow coals.
Broil about 20 minutes; then turn meat side down and broil till nicely browned, about 10 minutes.
Again turn meat side up, brush with sauce and continue broiling without turning about 30 minutes or till meat is well done.
Brush frequently with sauce.
