When preparing pork belly, it's crucial to ensure it is cooked until tender. This can be achieved by simmering it gently in the fermented fish sauce and water mixture for about 20 minutes. This slow cooking process allows the pork belly to absorb the rich flavors of the broth, resulting in a more flavorful and tender meat. Additionally, when adding the shrimp and catfish, make sure not to overcook them. Shrimp should turn pink and opaque, while catfish should flake easily with a fork. Overcooking can lead to a tough and rubbery texture, which can detract from the overall enjoyment of the dish.
