Preheat your oven to 300°F (150°C) and line a baking sheet with parchment paper or foil.
In a small bowl, combine the smoked paprika, garlic powder, onion powder, sea salt, and black pepper to create a dry rub.
Pat the pork ribs dry with a paper towel and apply the dry rub evenly to both sides of the meat.
Wrap the seasoned ribs tightly in a double layer of aluminum foil and place them on the prepared baking sheet.
Bake the ribs for approximately 2 hours, or until the meat is tender and begins to pull away from the bone.
While the ribs bake, whisk together the maple syrup, apple cider vinegar, Dijon mustard, and tomato paste in a small saucepan over low heat until thickened slightly.
Carefully remove the ribs from the oven, unwrap the foil, and brush the tangy glaze generously over the top of the meat.
Switch the oven to the broiler setting and return the ribs to the oven for 3 to 5 minutes until the glaze is bubbling and caramelized.
Allow the ribs to rest for 5 minutes before slicing and serving.
