Ingredients

12 whole prawns
5 tablespoons olive oil
1 onion, finely chopped
1 carrot, grated
2 celery sticks, finely chopped
finely grated zest of 1 lemon
1 red chilli, seeds removed, finely chopped
2 tablespoons flour
2 tablespoons finely chopped parsley, chives or chervil
½ teaspoon dried dill (optional)
¼ cup crème fraîche (optional)
500g medium-firm white fish such as gurnard
250g smoked fish
5 medium-sized floury baking potatoes such as Agria, peeled
4 tablespoons (60g) butter, melted

I had a request for a fish pie that had a very crunchy top and this is where I landed. This pie is topped with two styles of potato – first mash, then a layer of grated potato to get a lovely golden crunch. The pie has lots of fresh fish but no traditional white sauce, instead using a prawn stock to get a rich umami flavour. If you like a creamy sauce, you can add some crème fraîche.
