Grease
a rectangular baking dish. Wash and dry fish thoroughly.
Blot out water by wrapping fish in a clean towel.
This is
important so that excess water does not accumulate during
baking. Layer the dish as follows: fillets of fish, white
sauce, ground green chutney, tomato ketchup, some more white
sauce and sprinkle the top with grated cheese.
Bake at
gas mark 3/160º C for 10-15 minutes only. Overbaking will
spoil the fish.
