Method
- 1.
Par-boil the potatoes — Boil the potatoes in a large pot of well-salted water for about 15 minutes, until almost tender but still holding their shape.
- 2.
Poach the cod on top — Lay the cod on top of the potatoes, put the lid on and poach for 5-6 minutes, until the fish is opaque and flakes at the touch of a fork. Lift the fish out, drain the potatoes and set both aside.
- 3.
Sweat the onion and make a roux — Dry out the pot, melt the butter in it and soften the onion over medium-low heat for 5 minutes, until translucent and sweet with no colour. Stir in the flour and cook for a minute.
- 4.
Build the white sauce — Whisk in the milk a little at a time, keeping the sauce smooth, then simmer for 5 minutes until it is thick enough to hold a channel when you draw a spoon across the base.
- 5.
Crush it all together — Return the potatoes and fish to the pot and crush them into the sauce with a wooden spoon. Plokkfiskur should keep visible flakes of cod and lumps of potato — stop well before it becomes a purée. Season with the salt and white pepper.
- 6.
Warm through and top with chives — Warm through over low heat for 3-4 minutes, stirring, then scatter with the chives and serve straight from the pot with buttered rye bread.
