Scale and wash
the mullet. Cut through the belly and remove the
insides.
Break the spine
bone at the head and tail ends and carefully remove
it. Remove the flesh away from the skin on both
sides, leaving the head and tail intact.
Pick out and
discard any small bones remaining in the flesh. Chop
the flesh. Add the finely chopped ginger and onion,
seasonings and sherry and the prawns. Mix all
together to a smooth paste.
Spread the
mullet, inside up, on a board and sprinkle the
corn-flour all over it. Add the paste and bring the
skin on each side over it to shape the fish into its
original form, patting it well so that the skin will
adhere to the stuffing.
Place the fish on
an oiled oval plate, steam it for 15 minutes and
serve.
