Instructions
If using frozen catfish, defrost and rinse it with water and a bit of ginger to remove any fishy smell. Pat the fish dry with paper towels.
Season the catfish with fish sauce, sugar, salt, and sliced scallions. Let it marinate for at least 30 minutes to absorb the flavors.
In a heavy-bottomed pot, heat the cooking oil and sugar over medium heat. Stir until the sugar melts and turns an amber color.
Quickly add the marinated catfish to the pot. Turn off the heat and sear the fish on both sides, ensuring it’s coated in the caramel sauce.
Pour the marinade into the pot along with enough boiling water to just cover the fish. Add the peppercorns. Cover with a lid and simmer on low heat for at least 1 hour. (For an even richer flavor, braise for 2-3 hours.) Avoid stirring or moving the fish during this time, as it becomes very tender and can easily break apart.
If there’s too much liquid after braising, remove the lid and cook over medium-high heat until the sauce thickens to your desired consistency.
