"Good rib rub" - Kind of a loaded request. Everybody has different tastes. I make my own from dried herbs/spices/seasonings. Combine (to your taste) - Tenderquik salt, sage, rosemary, thyme, sugar (white or brown), pepper (black, white or hot) and paprica. Grind together in a blender or food processor. Rub liberally on ribs, cover and refrigerate overnight. Sear ribs both sides (on gtill) then drop heat to low and spray with liquid (preferably apple juice or diluted vineger) ant least every half hour for 3 or 4 hours or longer. The sage is something that goes real well with pork ribs. Works for pork shoulder roasts, too, just takes longer to cook.
