Clean the pork pata by washing it and removing any remaining hairs if any.
Put water in a cooking pot and add bay leaves, peppercorn, crushed garlic, onion and 1 tablespoon salt. Add in the pork leg making sure it is submerged in the water. Boil it for 2 hours or until pork leg is tender.
Remove pork from the pot. Let it cool and dry for 20 minutes. Then rub the salt all over the pork.
Heat oil in the pan and fry the pork leg until golden brown and crispy, flipping the other side as needed.
Transfer to a wire rack to drain excess oil.
Place it to a serving plate and serve with the crispy pata dipping sauce.
