My Norwegian Grandfather was born in Minnesota and migrated as a child to a Norwegian community in Alberta. In the 80s I went with my grandparents to an annual Lutefisk dinner, and they didn't eat the Lutefisk, nor would they let me try it. Too disgusting, they said. I've never actually tasted it.
Lefse however is the most popular traditional Norwegian dish that we make at Christmas (Lefse is basically a tortilla shell made with potatoes instead of corn or flour). While we regard lefse to be some kind of sacrosanct traditional Norwegian cuisine, in Norway they sell hotdogs wrapped in lefse.
