Pemmican

Pemmican is a concentrated mixture of fat and protein used as a nutritious food. The word comes from the Cree word pimîhkân, which itself is derived from the word pimî, "fat, grease". It was invented by the native peoples of North America. It was widely adopted as a high-energy food by Europeans involved in the fur trade and later by Arctic and Antarctic explorers, such as Sir Ernest Henry Shackleton, Fridtjof Nansen, Robert Falcon Scott and Roald Amundsen.
