I have never eaten Lutefisk (fish (cod) in lye). I refuse to eat food that is so dirty it has to be cleaned in lye. No idea what kind of "korv" you have eaten. I love Swedish "falukorv", and for those who are not into the Swedish language, korv simply means sausage, as in franks and that sort of things. In Norway we do not say korv, we say Pølse, but we can not ask for pølse in Sweden, or it would be spelled pölse and is the same or similar to the Scottish "haggis". Oh man language is just plain fun. And when the Vikings roamed around on this same globe, they say Norwegians, Swedes, Danes, Germans, Dutch, people in Belgium, France, and England could understand each other. Their languages were that similar. And now we are like, huh,.... how did you make that sound. lol
Anyway, I am a huge fish snobb, and extremely picky when it comes to seafood. My uncles were fishermen, so I am used to the best quality you can get. If not, I become grumpy. LOL, sort of like John Gustafson (Jack Lemmon) and Max Goldman (Walter Matthau). That is me when I get bad fish. :D :D :D We had poached cod today for dinner, potatoes, rutabaga stew and small pieces of bacon. My wife said, why does bacon go so well with fish. I asked, have you never seen that used in the US. No, never, was her answer. When it gets colder in the air I will smoke cod in my smoker (cold smoke it) then poach it, also with potatoes, rutabaga stew and bacon. First time I served that to my wife she said, "why haven't you served this to me before". :)
