- 2 chunky fillets of natural dyed smoked haddock – skinned, boned and cut into large chunks
- 8 large fillets of Dover sole cut into large bite-sized chunks
- 1.2 litres (1¾ pt) whole milk
- 1 kg (2 lb) mussels in shells or 250g (9 oz) mussels out of their shells
- 20 ml (1½ fl oz) white wine
- 2 generous handfuls of already cooked prawns – (ideally, Norwegian ones cooked in brine)
- 100 g (3½ oz or a handful) of frozen peas
- 100 g (3½ oz or a handful) of sliced, small button mushrooms
- 2 tablespoons chopped flat leaf parsley
- 130 g (4½ oz) butter
- 120 g (4 oz) plain flour
- Fish milk reserved from poaching.
- 900 g (2 lb) potatoes, boiled and mashed
- 50 ml (2 fl oz) fish milk reserved from poaching
- 50 g (2 oz) grated cheddar cheese
- 25 g (1 oz) butter
- Green beans
- Place the haddock and Dover sole in a wide bottomed pan.
- Add the whole milk and bring to a simmer.
- Carefully remove the cooked fish and set aside for later. Reserve 50ml of the milk for the cheesy mash and the rest for the sauce.
- Before cooking, remove and throw away any mussels which are open.
- Steam the mussels by throwing them into a hot pan and add a splash of white wine. Cover the pan and cook for 1 minute. Strain using a colander.
- Throw away any mussels which are still closed. Pick the mussels from their shells and add to the cooked fish.
- Melt the butter in a pan. Stir in the flour and cook for about 2 minutes without colouring.
- Gradually add the milk in stages, stirring constantly between each addition.
- Keep stirring to make a smooth sauce – you want to achieve a thick, double cream consistency.
- Simmer for about 10 minutes.
Add the reserved fish milk, cheese and butter to the boiled and mashed potatoes.
To make the pie
- Pre-heat the oven to 200°C/400°F/Gas Mark 6.
- Place the fish and mussels in an oven-proof pie dish (14” x 10”) off the heat.
- Pour on the sauce so that it covers the fish.
- Add the prawns, mussels, peas, mushrooms and parsley.
- Season the mixture and stir well, taking care not to over mix and break up the fish.
- Carefully cover the fish filling with the mash, and season it if necessary.
- Dot the butter over the mash for a crispy topping.
- Bake in the hot oven for 20 minutes until hot.
Serve straight away with green beans.
