In a large pot or Dutch oven, brown the oxtail pieces over medium-high heat. Remove and set aside.
Add onion and garlic to the pot and sauté until softened.
Stir in allspice, ginger, nutmeg, and cinnamon. Cook for 1 minute.
Return oxtail to the pot. Add beef broth, water, soy sauce, and Worcestershire sauce. Bring to a boil, then reduce heat to low, cover, and simmer for at least 2 hours, or until oxtail is very tender.
