Preheat your oven to 300°F (150°C).
Pat the baby back ribs dry with paper towels and coat them thoroughly with a dry rub of smoked paprika, garlic powder, onion powder, sea salt, and black pepper.
Wrap the seasoned ribs tightly in a double layer of heavy-duty aluminum foil, place on a baking sheet, and roast for 2 hours until the meat is tender and pulling away from the bone.
In a small bowl, whisk together the tomato paste, 1 tbsp of apple cider vinegar, honey, and Dijon mustard to create a clean and tangy BBQ glaze.
Carefully unwrap the ribs, brush the glaze generously over the meat side, and place them under the broiler for 3 to 5 minutes until the sauce is bubbly and caramelized.
While the ribs rest, toss the shredded cabbage with the remaining 1 tbsp of apple cider vinegar and celery seed in a medium bowl for a bright, crunchy side.
Slice the ribs between the bones and serve immediately alongside the fresh cabbage slaw.
