Some of the stuff around here that others might see as strange:
Blood sausage: (also known as Black sausage). Basically congealed blood mixed with a lot of other junk and fried up as a breakfast sausage. Never tried this one, but I don't really care to.
Lefse: Mashed potatoes mixed with flour, milk, oil etc. and fried like a tortilla. This one is AMAZING!! It is often eaten by spreading with butter and rolling it up. Some also sprinkle sugar on it for a dessert.
Lutefisk: cod fish aged in a lye solution which is then soaked off and the fish is cooked with lots of butter and other amazing things. But as my dad would say: "Rotten fish soaked in poison."
