Dried Fish

Fresh fish rapidly deteriorates unless some way can be found to preserve it. Drying is a method of food preservation that works by removing water from the food, which inhibits the growth of microorganisms. Open air drying using sun and wind has been practiced since ancient times to preserve food."Historical Origins of Food Preservation."
Accessed June 2011. Water is usually removed by evaporation (air drying, sun drying, smoking or wind drying) but, in the case of freeze-drying, food is first frozen and then the water is removed by sublimation. Bacteria, yeasts and molds need the water in the food to grow, and drying effectively prevents them from surviving in the food.

Fish are preserved through such traditional methods as drying, smoking and salting.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.

Types

Stockfish

Stockfish is unsalted fish, especially cod, dried by cold air and wind on wooden racks on the foreshore. The drying racks are known as fish flakes. Cod is the most common fish used in stockfish production, though other whitefish, such as pollock, haddock, ling and cusk, are also used.

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.

Stockfish is cured in a process called fermentation where cold adapted bacteria matures the fish, similar to the maturing process of cheese. Clipfish is processed in a chemical curing process called saltmaturing, similar to the maturing processes of other saltmatured products like the Parma ham.

Other

* Bacalhau is the Portuguese word for codfish and in a culinary context refers to dried and salted codfish. Fresh (unsalted) cod is referred to as ''bacalhau fresco'' (fresh cod). Bacalhau dishes are common in Portugal and Galicia, in the northwest of Spain, and to a lesser extent in former Portuguese colonies like Angola, Macau, and Brazil. There are said to be over 1000 recipes in Portugal alone and it can be considered the iconic ingredient of Portuguese cuisine (but curiously the only fish that is not consumed fresh in this fish-loving nation). It is often cooked on social occasions and is the Portuguese traditional Christmas dinner in some parts of Portugal.
* Mackerel (Sukho Bangdo in Konkani language) is dried in Goa since ancient times. If preserved well they can stay for many years. Prawn and shark are also dried in Goa.
* Baccalà (in Venetian language: bacalà) is sun-dried stockfish, rather than salt cod. In other parts of Italy dishes made with salt cod are given the same name. Baccalà dishes made with stockfish are soaked for several days to soften the fish. Salt cod, which is already soft, is also soaked to remove excess salt.
* Balyk is the Russian term for the salted and dried soft parts of fish of large valuable species, such as sturgeon or salmon. Over time, the term has come to apply also to smoked fish of these species.
* Boknafisk is a variant of stockfish and is unsalted fish partially dried by sun and wind on drying flakes or on a wall. The most common fish used for boknafisk is cod, but other types of fish can also be used. If herring is used, the dish is called ''boknasild''.
* '' Bugeo'' refers to dried Alaska pollock.
* '' Daing'' (also known as ''bulad'' or ''tuyô'') refers to sun-dried fish in the Philippines. Almost any kind of fish is used, but the most popular variant uses rabbitfish (locally known as ''danggit''). Cuttlefish and squid may also dried this way The amount of drying can vary. In the ''labtingaw'' variant, the drying period only lasts a few hours, allowing the fish to retain some moisture and texture. In the ''lamayo'' variant, the fish isn't dried at all, but simply marinated in vinegar, garlic and spices.
* Dried squid
* Fesikh is a traditional Egyptian fish dish consisting of fermented salted and dried gray mullet, of the mugil family, a saltwater fish that lives in both the Mediterranean and the Red Seas. The traditional process of preparing it is to dry the fish in the sun before preserving it in salt.
* Gwamegi is a Korean half-dried Pacific herring or Pacific saury made during winter. It is mostly eaten in the region of North Gyeongsang Province such as Pohang, Uljin, and Yeongdeok where a large amount of the fish are harvested. Guryongpo Harbor in Pohang is the most famous. Fresh herring or saury is frozen at -10 degrees Celsius and is placed outdoors in December to repeat freezing at night and defreezing in the day. The process continues until the water content of the fish drops to approximately 40%.Gwamegi

The Phoenicians had learned to dry tuna in sea salt so they could trade it. Mojama is made by curing tuna in salt for two days. The salt is then removed, the tuna is washed and then laid out to dry in the sun and the breeze (according to the traditional method) for fifteen to twenty days.

Water activity

The water activity, a_w, in a fish is defined as the ratio of the water vapour pressure in the flesh of the fish to the vapour pressure of pure water at the same temperature and pressure. It ranges between 0 and 1, and is a parameter that measures how available the water is in the flesh of the fish. Available water is necessary for the microbial and enzymatic reactions involved in spoilage. There are a number of techniques that have been or are used to tie up the available water or remove it by reducing the a_w. Traditionally, techniques such as drying, salting and smoking have been used, and have been used for thousands of years. These techniques can be very simple, for example, by using solar drying. In more recent times, freeze-drying, water binding humectants, and fully automated equipment with temperature and humidity control have been added. Often a combination of these techniques is used.FAO

History

Salt cod has been produced for at least 500 years, since the time of the European discoveries of the New World. Before refrigeration, there was a need to preserve the codfish; drying and salting are ancient techniques to preserve nutrients and the process makes the codfish tastier.

The Portuguese tried to use this method of drying and salting on several varieties of fish from their waters, but the ideal fish came from much further north. With the "discovery" of Newfoundland in 1497, long after the Basque whalers arrived in Channel-Port aux Basques, they started fishing its cod-rich Grand Banks. Thus, ' became a staple of the Portuguese cuisine, nicknamed ' (faithful friend). From the 18th century, the town of Kristiansund in 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, Lent, and other festivals) on which the Church forbade the eating of meat. ' dishes were eaten instead.
