I've cooked also salmon when I lived in Norway, but nothing like this... In my case it was about making it as simple as I could so I only let the salmon in the oven for about half an hour at 100°C, boil some basmati rice and put some butter in it after I got it out of the water. Then I would add some sour creme on top of the salmon, condiments and garlic and that's it.
Now after seeing your recipe I think I ate my salmon the wrong way...
I will bookmark your post to try the recipe in the future though.
