Small bunch parsley, chopped
12 sustainable hand-dived scallops and 6 shells, cleaned

You’ll also need

Potato ricer (or see tips)
Piping bags

Method

For the white sauce: melt the butter in a pan over a medium heat, then whisk in the flour and cook for 2 minutes. Whisk in the milk, then simmer until bubbling. Stir in the parsley and season with salt and pepper.
Divide the scallops and prawns among the shells, pour over the sauce, then leave to cool.
Cook the potatoes in boiling salted water for 20 minutes until soft, then drain and pass through a potato ricer into a bowl. Mix in the butter and yolks, then season and put in a piping bag.
Heat the oven to 180°C fan/gas 6. Pipe the potato mix around the edges of the shells, then sit them on a baking tray and bake for 15-20 minutes. Serve with lemon wedges (on a bed of rock salt if you’re feeling fancy).

No potato ricer? While the spuds are hot, push them through a sieve, in batches, using a wooden spoon.
