Place the salted cod in a pot of water and boil for 15 minutes, then drain and repeat with fresh water to remove excess salt.
Drain the fish, let it cool slightly, and use your fingers or a fork to flake it into small bite-sized pieces, removing any skin or bones.
Heat the coconut oil in a large skillet over medium heat.
Add the sliced onion, minced garlic, chopped scallion, and sliced bell pepper to the skillet and sauté until the onion is translucent.
Stir in the chopped tomato, thyme sprigs, and the finely minced scotch bonnet pepper, cooking for another 3 minutes.
Add the flaked saltfish and black pepper to the pan, tossing gently to combine with the aromatics.
Carefully fold in the drained ackee, taking care not to over-stir so the delicate fruit remains in large, yellow chunks.
Cover the skillet and simmer on low for 5 minutes until the ackee is heated through and the flavors are perfectly melded.
