In a large bowl, season the oxtails with the paprika, garlic powder, salt, black pepper, onion powder and browning sauce. Mix everything together.
In a large pot, warm the oil then cook the oxtails on each side for 5-7 minutes. Remove when it's done.
Add the pimento peppers, onion, garlic, scallions and bell pepper. Cook for 2-3 minutes.
Place the oxtails back into the pot along with the water, tomato paste, thyme, salt, parsley, scotch bonnet ( if using) and the marinade (if you have any leftovers). Mix everything.
Cover and let it cook for 1-1/2 hours.
