[Grandidier (1899), p. 521] The oldest traditional way of preserving fish was to let the wind and sun dry it.
Drying food is the world's oldest known preservation method, and dried fish has a storage life of several years. The method is cheap and effective in suitable climates; the work can be done by the fisherman and family, and the resulting product is easily transported to market.

Clipfish
Over the centuries, several variants of dried fish have evolved. Stockfish, dried as fresh fish and not salted, is often confused with
clipfish, where the fish is salted before drying. After 2–3 weeks in salt the fish has saltmatured, and is transformed from wet salted fish to Clipfish through a drying process. The salted fish was earlier dried on rocks (clips) on the foreshore. The production method of Clipfish (or Bacalhau in Portuguese) was developed by the Portuguese who first mined salt near the brackish water of Aveiro, and brought it to Newfoundland where cod was available in massive quantities. (''q.v.'').
Salting was not economically feasible until the 17th century, when cheap salt from southern Europe became available to the maritime nations of northern Europe.

Norway became an important place of purchasing ''bacalhau'' or ''klippfisk'' (literally "cliff fish", since the fish was dried on stone cliffs by the sea to begin with.) Since the method was introduced by the Dutchman Jappe Ippes around 1690, the town had produced klippfisk and when the Spanish merchants arrived, it became a big industry. The bacalhau or bacalao dish is sometimes said to originate from Kristiansund, where it was introduced by the Spanish and Portuguese fish buyers and became very popular. Bacalao was common food in northwest Norway to this day, as it was cheap to make. In more recent years, it has become less of an everyday staple and mostly eaten on special occasions.
This dish was also popular in Portugal and other Roman Catholic countries, because of the many days (Fridays,
