I will join you in the first two but I am not eating Ludefisk (the piece of cod that passes all understanding) again.
I have had it at a Sons of Norway Banquet and at Lutheran church supper. If the Lutherans can not make it edible no one can.
You need to find a bottle of Norwegian Akvavit (potato based, so I guess it is Vodka). I remember having it as a kid. All I can recall is that it had an oily taste and texture to it. Looking it up just now, that is due to the use of caraway and dill seeds used in the process.
