Lutefisk (lutfisk), in Norway, in Sweden and the Swedish-speaking areas in Finland (lipeäkala in Finnish) is a traditional dish of the Nordic countries made from stockfish (air-dried whitefish) and soda lye (lut). Its name literally means "lye fish", owing to the fact that it is made with caustic soda or potash lye.
Preparation
Lutefisk in a Norwegian market.Lutefisk is made from air-dried whitefish (normally cod, but ling is also used), prepared with lye, in a sequence of particular treatments. The first treatment is to soak the stockfish in cold water for five to six days (with the water changed daily). The saturated stockfish is then soaked in an unchanged solution of cold water and lye for an additional two days. The fish will swell during this soaking, attaining an even larger size than in its original (undried) state, while its protein content decreases by more than 50 percent, producing its famous jelly-like consistency. When this treatment is finished, the fish (saturated with lye) has a pH value of 11–12, and is therefore caustic. To make the fish edible, a final treatment of yet another four to six days of soaking in cold water (also changed daily) is needed. Eventually, the lutefisk is ready to be cooked.
In Finland, the traditional reagent used is birch ash. It contains high amounts of potassium carbonate and hydrocarbonate, giving the fish more mellow treatment than sodium hydroxide (lyestone). It is important to not incubate the fish too long in the lye, because saponification of the fish fats may occur, effectively rendering the fish fats into soap. The term for such spoiled fish in Finnish is saippuakala (soap fish).
Cooking
Cooking pots at a church supper: with this method, the lutefisk was boiled for about five minutes, until translucent, then promptly served.After the preparation, the lutefisk is saturated with water and must therefore be cooked carefully so that it does not fall into pieces.
Lutefisk does not need any additional water for the cooking; it is sufficient to place it in a pan, salt it, seal the lid tightly, and let it steam cook under a very low heat for 20–25 minutes. It is also possible to do this in an oven. There, the fish is put in an ovenproof dish, covered with aluminium foil, and baked at 225 °C (435 °F) for 40–50 minutes.
Another option is to parboil lutefisk. Wrap the lutefisk in cheesecloth and gently boil until tender. This usually takes a very short time, so care must be taken to watch the fish and remove it before it is ready to fall apart. Prepare a white sauce to serve over the lutefisk.
Lutefisk sold in North America may also be cooked in a microwave oven. The average cooking time is 8-10 minutes per whole fish (a package of two fish sides) at high power in a covered glass cooking dish, preferably made of heat resistant glass. The cooking time will vary, depending upon the power of the microwave oven.
When cooking and eating lutefisk, it is important to clean the lutefisk and its residue off of pans, plates, and utensils immediately. Lutefisk left overnight becomes nearly impossible to remove. Sterling silver should never be used in the cooking, serving or eating of lutefisk, which will permanently ruin silver. Stainless steel utensils are recommended instead.
Eating

Lutefisk is also very popular in Nordic-North American areas of Canada, especially the prairie regions and the large Finnish community at Sointula on Malcolm Island in the province of British Columbia, and the United States, particularly in the Upper Midwest.
Lutefisk is usually served with a variety of side dishes, including, but not limited to, bacon, green peas, green pea stew, potatoes, lefse, gravy, mashed rutabaga, white sauce, melted or clarified butter, syrup, geitost (goat cheese), or "old" cheese (gammelost). In the United States, in particular, it is sometimes eaten together with meatballs. Side dishes vary greatly from family to family and region to region, and can be a source of jovial contention when eaters of different "traditions" of lutefisk dine together.
Today, akvavit and beer often accompany the meal due to its use at festive and ceremonial occasions (and most eaters, regardless of side dish preferences, will argue that these beverages complement the meal perfectly). This is a recent innovation, however; due to its preservative qualities, lutefisk has traditionally been a common "everyday" meal in wintertime.
The dish has sometimes subjected Nordic-Americans to jokes about the personality traits "produced" as a side effect of the consumption of chemically-treated white fish. Lutefisk prepared from cod is somewhat notorious, even in Scandinavia, for its intense odor. Conversely, lutefisk prepared from pollock or haddock contains almost no odor.
Lutefisk has its fair share of devotees: in 2001, Norwegians consumed 2,055 tonnes of lutefisk in their homes and approximately 560 tonnes in restaurants[citation needed]. (To put this quantity in perspective, 2400 tons would fill approximately 80 full size semi trucks or a medium length goods train). Annual sales of lutefisk in North America exceed those in Norway.
The taste of well prepared lutefisk is very mild, and often the white sauce is spiced with pepper or other strong tasting spices to bring out the flavour.
