Reheating/Freezing Instructions: The cooked ribs will keep in a covered container in the refrigerator for 3 to 4 days, or they can be frozen for up to 3 months. To reheat, thaw the ribs overnight in the refrigerator if necessary, then place on a foil-lined baking sheet. Brush the ribs with another layer of BBQ sauce and cover tightly with foil. Warm in a 250°F oven for 30 to 35 minutes, or until warmed through. Remove the foil and continue cooking for 10 to 15 minutes to allow the sauce to set and the bark to crisp up.
