Ribs are best eaten same-day. If you do have leftovers, I recommend removing the meat from the bones before refrigerating them. It's just easier when they're still in that "fall off the bone" stage. Once you refrigerate them, the fat in the meat firms up and it's much harder to cleanly remove the meat from the bones. Use the shredded meat in fried rice, stir fry, bao buns, BBQ pizza, or grilled cheese. You can even save the bones in the freezer for the next time you make stock or bone broth.
