Start by giving the goat meat a proper bath in flavor. In a large bowl, combine the goat meat with lime juice, vinegar, garlic, ginger, scallions, chopped onion, thyme, allspice, salt, pepper, and 1 tablespoon of curry powder. Mix well with your hands or a spoon, ensuring every piece is coated. Cover and marinate for at least 4 hours—overnight is best for flavor penetration.
