Dried food is the longest lasting food in the game. It can nearly last for a whole year.
In order to make dried meat or dried fish, you need a wall (or a kota Framework, or the side of a shelter), tying equipment and obviously meat or fish. Dried food can be made only in the winter and early spring. As with smoked meat, the most efficient use of your cords would be to use 1 cord and 19 cuts at a time.
