I have based my recipe here on Mary Berry’s fish pie as I love her addition of the boiled eggs!
5g butter, plus extra for greasing
1 large onion, roughly chopped
50g plain flour
570ml/1 pint milk
salt and freshly ground black pepper
2 tbsp lemon juice
350g salmon, cut into 1cm/½in pieces
200g smoked haddock, cut into 1cm/½in pieces
350g haddock, cut into 1cm/½in pieces
4 hard-boiled free-range eggs, roughly chopped
For the topping:
900g potatoes, peeled and cut into even-sized pieces
Couple of handfuls of frozen peas
about 8 tbsp hot milk
about 50g butter
Preheat the oven 200C/400F/Gas 6. Grease a shallow 2.5 litre/4½pint dish with butter.
Melt the butter in a pan on a high heat and fry onion for few minutes. Lower the heat, cover and leave to soften for 15 minutes.
Remove the lid and increase the heat to remove any moisture. Sprinkle in the flour and then add the milk gradually, stirring well and allowing the sauce to thicken until all the milk has been added.
Season with salt and freshly ground black pepper, add lemon juice and the raw fish and cook for couple of minutes, stirring continuously until the fish has just cooked. Stir in the smoked haddock. Pour the mixture into the buttered dish and leave to cool. Top with the hard-boiled eggs.
For the topping, boil the potatoes in a pan of salted water until tender. When the potatoes are almost done add the frozen peas and cook for a further minute. Drain, tip the potatoes back into the pan, add milk and butter and mash until lump-free. Add salt and freshly ground black pepper to taste.
Spread the mash over the top of the sauce and fish in the dish and score with a fork.
Bake in the preheated oven for about 30 minutes or until the potato is crisp and golden brown.
