It is Kiviak, a traditional diet originated from the Inuit people in Greenland. It is a fermented meat food made by stuffing raw puffins into raw seals. Because it is rich in vitamins, it is an important source of supplementation in the harsh cold environment of Greenland.

"Human Planet" is a documentary about human survival launched by the BBC, directed by Tom?Hugh-Jones?,?Tuppence?Stone?, Nicolas?Brown?, Mark?Flowers?, and John Hurt Serve as narrator.

The film mainly tells the survival of people living in all corners of the world, from remote deserts to bustling cities. Each episode focuses on an iconic geographical environment, revealing how people there adapt to the environment and the changes and reproduction of surrounding plant and animal species.

How to make pickled puffins:

Take a piece of sealskin and stuff the sealskin with dead seabirds, at least 500 of them. Sew the sealskin shut, making sure to squeeze out all the air. Seal fat repels flies, so don't hesitate to apply more to the seams. Finally, cover it with a large rock to ensure no more air can get in. Frozen land is a natural refrigerator.

After three months, these little puffins stored in the summer become a delicacy called Kiviak by the Inuit. The Inuit of Northern Greenland love kiviak so much that it is a must-have dish at birthdays and weddings. Moreover, Kiviak is very nutritious and full of vitamins and minerals, which can help people survive the cold winter months.
