For me, it's kompe. It's a dish that's eaten in southern Norway, which consists of a little ball of salt pork surrounded by a potato dumpling. As the dumping is boiled, the flavor of the pork spreads through the potato, and it's a way to make a very poor meal feel like much more.
Most often eaten with butter, sugar, and lingonberry jam, I think the leftovers fried up on the second day are the best!
