OK, lutefisk probably isn't a super popular dish, so you may not have even heard of it. But we simply can't talk about acquired tastes and not bring up lutefisk. Lutefisk is dried cod that's soaked in a lye solution, then soaked in water, and then boiled or baked and served with butter, salt and pepper. Some say it has the consistency of gelatin. That's right -- gelatin. And it also has a very strong smell. Norwegians traditionally serve it at holidays, like Christmas.
