Store any leftovers in an airtight container in the fridge for up to 4 days. These actually taste even better the next day as the spices continue to settle into the meat. To reheat wrap the ribs in foil with a splash of water or extra sauce to keep them moist. Put them in a 300°F oven for 15 minutes until they're warmed through. Avoid the microwave if you can because it tends to make the meat rubbery and the sauce oily.
