To make a pork leg roast, prepare a seasoning mix of onion, scallion, scotch bonnet, garlic, thyme, salt, and black pepper. Score the pork skin, make holes in the roast, and stuff them with the seasoning. Season the exterior with salt and pepper, then marinate overnight. Brown the pork on both sides in hot coconut oil in a Dutch pot, then add water and simmer on low heat, adding water as needed, until tender. Let the roast rest before serving. For the gravy, use the drippings, add onion, thyme, and Pickapeppa sauce, then thicken with a cornstarch-water mixture. Serve with rice, peas, and vegetables.
