Apply little salt and lime juice on the fish pieces and wash it with water. Drain the water. Grind together ingredients listed from ginger- garlic to salt into a fine paste adding a little water. Make gashes in the fish pieces and marinate the pieces with the ground paste. Keep the marinated fish for half an hour. Heat oil in a pan and shallow fry the fish pieces.Serve with onion rings and a slice of lime.
Notes
Please adjust the qty of spices to suit your taste. The ground paste should not be watery (1/2 - 1 tsp of water is enough while grinding the masala). I usually fry the fish pieces on low-medium flame. Also you can add some fresh curry leaves while frying the fish pieces. You can use the same masala for any kind of fish.
