Fermented fish

Fermented fish is an Eskimo food that is eaten raw and frozen. It is a staple part of the diet in many Yupik communities of the Yukon-Kuskokwim Delta.

Preparation
Fermented fish is prepared by first digging a hole about two feet in the ground. The preparer places a freshly caught fish in the hole, covers it with earth, and lets it stay buried for a couple weeks to a month or longer. After the fish reaches a desired level of fermentation, the preparer unearths it and immediately freezes it until someone is ready to eat it. Fermented fish tastes best raw and frozen.
