Method
Start by removing the skin from your pouting fillets and cut them into smaller pieces.Place the fish in a large saucepan along with the sliced leeks. Add the milk, bay leaves and peppercorns and bring to the boil. Reduce the heat and leave to simmer, very gently, for about 3–4 minutes, until both the fish and leeks are almost cooked. Turn off the heat but put a lid on the pan.
Preheat the oven to 180°C/350°F/gas mark 4.
To prepare the topping, place the dill in a mixing bowl. Add the lemon zest along with the breadcrumbs. Season with a good pinch of salt and pepper and mix well.
In a small pan, melt the butter, then pour it over the crumbs. Stir to coat everything thoroughly.
Remove the fish and leeks from the milk, discarding the peppercorns and bay leaves, but reserving the milk.
Melt the 50g (1¾oz) of butter in a cast-iron casserole dish, then stir in the flour to make a roux. Gradually ladle in the reserved milk and whisk the sauce together. Add the tarragon to the sauce, then the fish and leeks and season lightly. Scatter the buttered breadcrumb mixture over the top and bake for around 25 minutes until golden and crisp.
Spoon into warmed bowls and serve as it is or with a little buttered kale on the side.
