Clean and wash fish. Score the fish 3 times on each side with a sharp knife and place on a plate.
Drizzle with freshly squeezed lime juice and sprinkle with fish seasonin’ and salt on each side of the fish and leave to for ½ hour.
Mix all the ingredients for the escovitch sauce in a bowl and set aside.
Mix the flour, fish seasonin’ and salt on a plate.
Dust the fish in the flour mixture and shake off any excess before frying.
Pour oil in a heavy based frying pan so it is approximately 1cm deep for shallow frying. Heat the oil until it is around 180°c.
Fry the fish for 5 minutes on each side, until golden brown. Remove from the pan and place on a paper towel to soak up any excess oil.
Strain the escovitch vegetable mixture through a sieve and reserve vinegar. In a clean frying pan heat 1 tsp oil. Add the vegetable mixture and cook on a low to medium heat for 5-7 minutes. Reduce the heat to low, then add the reserved vinegar cover and cook for a further 3 minutes.
Place the fried fish in a serving dish and pour the hot vegetable mixture over the fish.
