Boil the Meat: Place the pork feet or ears in a large pot with 4 cups of water. Bring to a boil, reduce the heat, and simmer for 2 hours or until the meat is tender.
Prepare the Brine: In a separate bowl, mix the vinegar, lime juice, onion, garlic, salt, black pepper, allspice, and red pepper flakes.
Combine Meat and Brine: Once the meat is tender, drain and let it cool slightly. Place the meat in a bowl and pour the brine over it.
Marinate: Let the meat marinate in the refrigerator for at least 4 hours (overnight is best).
Serve: Garnish with parsley and cilantro. Serve chilled.
