Prepare the Ribs: Wash the ribs with lemon juice and cool water. Cut off most of the excess fat.
Marinate the Ribs: Season the ribs with salt, Caribbean green seasoning, Worcestershire sauce, and black pepper. Allow to marinate for at least an hour, or overnight for better flavor.
Caramelize the Sugar: Heat vegetable oil in a heavy pot over medium-high heat. Add brown sugar and caramelize it, being careful not to burn it.
Brown the Ribs: Add the marinated ribs to the pot and stir to coat with the caramelized sugar. Add water to cover the ribs and bring to a boil.
Simmer the Ribs: Reduce heat to a simmer and cook, covered, until the ribs are tender, about 1.5 hours. Add more water if necessary.
Add Final Ingredients: Add scallion, diced tomato, Scotch bonnet pepper, fresh thyme, and ginger. Simmer until the vegetables are soft.
Adjust and Serve: Adjust for salt, then increase heat to thicken the gravy to desired consistency. Finish with parsley and serve.
