Preheat oven to 450 degrees.
Use dry rub of choice, rub over approx 5 lbs of pork spare ribs.
Cook ribs in preheated oven 15 minutes, turn and cook an additional 15 minutes. Remove from oven, transfer to a slow cooker (I had to cut the rack in half to get it to fit), dump 1 whole bottle of your favorite bbq sauce over ribs. Cook on low 4 1/2 hours.
Remove from slow cooker and grill over medium heat about 6 mins. on each side, just to crisp the outside, basting with bbq sauce.
