Interesting. My wife is a Viking, so I have the answer as to why the viking men went sailing to the far corners of the earth, and it wasn’t for treasure.... ;-)
Like many cultures..my wife is of Serbian ancestry, was a HOT cheerleader type 40 years ago... Scandinavian gals look great but don’t have a long shelf life,
YMMV!
FWIW I would rather eat Eastern European food now than say lutefisk or eels...
