Remove the membrane from the ribs by loosening it with a dull knife and then peeling it off, as described above.
Season the ribs to taste on both side with sea salt and black pepper.
Place the ribs in a baking pan. Brown them in the oven for 10 to 12 minutes on each side and set aside.
In a bowl, combine together the ketchup, onion, pear, chili powder, paprika, oregano, apple cider vinegar, coconut aminos, and honey (if using), and season to taste with salt and pepper.
Place the ribs in your slow cooker, and pour in the sauce, making sure that all the meat is coated.
