Large wooden racks called hjell are for drying fish. They are a regular sight along the coast of Norway. Cod are hung on the wood in the open air for about three months in the Spring.
Temperatures just above freezing is best for drying the fish. If it gets too cold the fibers in the fish will burst and it will be uneatable. The snow protects the fish from insects and bacteria.
A lot of the fish is exported to Southern Europe or is used in Norway as Lutefisk or as a snack like beef jerky.
