The coating can be modified to suit your palate. You could add a pinch of brown sugar, ground cumin or oregano. The more flour used, the lower the (chilli) heat.
Combine the ingredients for the coating. Divide the fish into 4 servings. Dust with the coating.
Combine the ingredients for the salsa.
Heat a non-stick frying pan until hot. Cook the fish for about 1-2 minutes each side depending on the thickness. If preferred, you can add a teaspoon of oil to the pan but the fish won't be as black.
Serve with the salsa, a green salad and boiled rice.
