INGREDIENTS
- 300g of waxy potatoes, halved
- 250g skinless white fish
- 300ml milk
- 50g butter
- 1 leek, finely sliced
- 25g flour
- 2 tbsp. chopped parsley
- 2 tsp Dijon mustard
INSTRUCTIONS:
- Cook the potatoes in boiling salted water for 5-7 mins, until almost tender but firm enough to grate. Drain and refresh under cold running water. Put the fish in a shallow saucepan and pour over the milk. Bring to a simmer and cook for 5 mins. Drain the fish, reserving the milk, then set aside.
- Heat half the butter in a medium saucepan, add the leek, then cook for 5-6 mins until softened. Stir in the flour for 1 min, then remove from the heat. Gradually add the milk stirring well between each addition. Return to the heat and stir until the sauce comes to the boil. Simmer for 2 mins, then stir in the parsley and mustard.
- Heat the grill to high. Flake the fish into large chunks, fold into the sauce, then place in a small ovenproof dish. Coarsley grate the potatoes. Melt the remaining butter, toss with the potatoes, season and scatter over the dish. Place under a medium grill for 5-10mins until the potatoes are golden and tender.
