Place fingerling potatoes in cold water in a saucepan and bring to a boil. Cook for around 20 minutes (until potatoes are done). Peel potatoes and while they are still warm, dice up onto plate. Add a few pats of butter to top of potatoes. Put thin slices of salmon over potatoes and then spoon cream of chives dressing around potatoes and salmon. Add a few twigs of dill on top and squeeze a little bit of lemon juice over salmon.
