We have a sort of pathetic dishwasher in our kitchen. The Arm-Strong model (4 students' hands in the sinks) works MUCH better on dishes.
However sorry and excuse the machine is for dishes, it cooks fish just fine, thank you very much.
Not like this.
We take a nice filet of Salmon (or Char or Trout) and ensure there are no pin-bones. Add some lemon juice and slices of lemon (if nice ones are available) and some pepper and fresh dill. Wrap it tightly in THREE layers of tinfoil,
Remove, allow to rest for a few minutes then peel off the foil and serve!
What could be simpler?
Enjoy on simple rye or pumpernickel bread with a smear of very fine Kozliks's mustard.
