| 350g whiting fillets, cooked in 275ml semi-skimmed milk, then strained with the milk reserved|
| 50g butter|
| 40g plain flour|
| 4 large egg yolks |
| 2 tablespoons grated Parmesan cheese|
| 2 teaspoons lemon juice|
| 1 tablespoon finely chopped parsley|
| 1 teaspoon anchovy essence or paste|
| 3 spring onions, finely sliced|
| 5 large egg whites|
| Salt and cayenne pepper|
| Preheat the oven to 200˚C/400˚F/gas mark 6.|
Flake the fish, discarding the skin and bones as you go, then put it on one side while you make a sauce by melting the butter in a saucepan and stirring in the flour.
Cook this for a minute or two before gradually adding the strained milk. Bring to the boil, stirring, and boil gently for 1 minute.
Then remove the pan from the heat and beat in the egg yolks, 1 tablespoon of Parmesan cheese, the lemon juice, parsley, anchovy essence or paste, spring onions and the fish.
Season well with salt and ½ teaspoon of cayenne pepper.
Next whisk the egg whites to the stiff-peak stage.
Then fold them into the fish mixture, taste and season again if necessary.
Now pour the mixture into a buttered 1.7 litre soufflé dish or deep baking dish, and sprinkle with the remaining Parmesan cheese. Transfer the soufflé to the oven, placing it on a baking sheet, and turn down the heat immediately to 190˚C/375˚F/gas mark 5.
Cook for 35-40 minutes, or until the soufflé is well risen and golden brown, then serve absolutely immediately.
