Method:
1. Place the salmon in a baking dish. Add olive oil and season with salt and pepper on both sides. Squeeze some lemon on top.
2. Bake in the oven at 140 degrees Celsius for about 10 minutes.
3. Rinse the leek and slice it into fine pieces. Put the leek in a saucepan and heat until tender in the butter with a splash of water. Season to taste.
Method for the Sandefjord butter:
If you want to skip the smoking of the cream, go straight to point 2.
1. Place the cream in a deep dish inside a lime kiln. Fire up a pot of smoking chips. Close again and leave the cream to smoke for half an hour.
2. Reduce the cream by half, turn down the heat and beat in the butter. Keep whipping until all the butter is mixed in well. It is important that it does not boil, but is simply kept warm.
3. Season with lemon juice, salt, pepper, and chopped parsley.
Arrange the salmon on top of the leeks. Top with plenty of smoked sauce. Garnish with nasturtium. Enjoy!
