Clean and scale
the fish and score it diagonally on both sides.
Sprinkle with salt and leave to stand for 10
minutes.
Heat the oil and fry the fish until browned
on both sides, turning once and basting with oil as
you cook.
Add the ginger, spring onions, water,
soy sauce, wine or sherry and sugar, bring to the
boil, cover and simmer for 20 minutes until the fish is
cooked. Serve hot or cold.
