Many years ago (45 maybe ?) we went on a cruise along the coast of Norway on some sort of tramp steamer. I recall the menu was long on pickled herring, the antidote to which seemed to be some rather excellent cloud berry liqueur ("Lakka" I believe, served well iced). Can't say I've ever found it anywhere else; anyone have any suggestions for buying it in the uK ?
This worth a shot
This looks like the real deal
