This is a recipe for Lechon paksiw. Saute garlic and onion until soft. Add the peppercorns and bay leaves and cook for 2 minutes. Add the lechon. Stir and continue to cook for 2 to 3 minutes. Pour the lechon sauce and beef broth. Let boil. Cover and cook in low heat for 30 minutes or until the liquid reduces in half.
Heat oil in a pot. Add vinegar and water and bring to a boil, uncovered and without stirring, for about 3 to 5 minutes. Add lechon sauce and sugar. Stir. Add leftover lechon or lechon kawali and bay leaves. Lower heat, cover and continue to cook for about 15 to 20 minutes or until meat is tender. Add more water in ½ cup increments as needed.
Place leftover lechon meat in a wok or a pot. Add water, vinegar, soy sauce, sugar, garlic, onion, ground pepper, peppercorn and bay leaves to the wok. Bring to a quick boil and reduce heat. Simmer for 10-15 minutes or until meat is fully tender.
Chopped up lechon kawali, crispy pata, oven-roasted pork, or lechon manok are also great options to use. While this paksiw traditionally uses already-cooked meat, you can also start from scratch. Brown the pork and proceed with the recipe, adding more water or broth as needed to fully cook the meat.
