Preheat the oven to 230-250°F (110-120°C).
Season the meat with your chosen spices. (Optional: Let it marinate for at least 30 minutes to an hour for better flavor.)
Roast the meat in the oven for 8 hours or until it is fork-tender.
In a separate pan, sauté the garlic cloves in cooking oil.
In the pan with the garlic, combine Datu Puti soy sauce and brown sugar, and bring the mixture to a boil.
Once boiling, add Datu Puti vinegar and let the sauce boil again.
After the sauce has boiled, add the cooked meat along with bay leaves and peppercorns.
Simmer the mixture for additional flavor.
Serve the dish with steaming hot rice, garnished with strips of Indian mango.
