b. In a bowl, combine the brown sugar, fish sauce, soy sauce, water, minced garlic, and chopped shallots. Mix well until the sugar is dissolved.

c. Place the pork belly pieces in a large mixing bowl. Pour the marinade over the pork, ensuring all the pieces are coated evenly. Let it marinate for at least 30 minutes, allowing the flavors to penetrate the meat.

f. Reduce the heat to medium-low and continue cooking the pork belly for an additional 10 minutes, allowing it to caramelize.

a. Stir the pork belly occasionally to prevent it from sticking to the skillet and ensure even caramelization.

c. Adjust the heat if necessary to prevent the pork from burning.

d. Cook the pork belly for approximately 15-20 minutes in total until it is fully caramelized and has a glossy appearance.

e. Ensure that the pork belly is cooked through and no longer pink in the center.
