Preheat oven to 200 deg. C
Wash catfish, cut open the belly and remove the gut. (A post on how to do this coming soon).
Rinse and dry the gut. Using a sharp knife make slits about 1 inch apart across the body.
Using a sharp knife score the fish by making slits about 1 inch apart across the body of the fish. The Cut should be deep about halfway between the skin and the bone.
Sprinkle some salt all over the skin of the fish, the gut cavity and into the slits.
Cut out enough aluminium foil to cover the whole catfish.
Spread on a baking tray and rub all over with some vegetable oil.
Lay fish on the foil and pour your pepper mix all over the fish, into the slits and the gut cavity.
Flip the fish and repeat.
Drizzle a little oil all over the fish and wrap folding foil lengthwise.
Make sure every part of the fish is covered and well-sealed so that the juices will not leak out and there will be even circulation of heat.
