The documentary of Eskimo pickled puffins is "The Planet of Man". Pickled puffins, a kind of food, once appeared in the BBC documentary "Planet of Man". Its English name is Kiviak, commonly known as pickled puffins, and it is a special food for Eskimos. Eskimos are distributed in Greenland, Canada, Russia and other regions, so canned pickled puffins can be seen in these places. People who have smelled its bad smell naturally regard it as the first place in "dark cuisine", and those so-called "dark cuisine" in Korea are simply not worth mentioning.
