Apropos salt in coffee, the way I heard it when growing up was that coffee brewed (or rather boiled) on meltwater didn't quite taste right, add some salt and presto! Having tried that myself I can easily believe that, meltwater doesn't taste the same as well-water. For the record, I tried myself, and yes, when boiling instead of brewing some salt will work, in brewed coffee though, not!
My brother's wife is no Sami, just a regular fin, and she, and her mother and sisters, actually use salt in coffee. To me as a regular Swede it's sort of insane.
