Harðfiskur – Icelandic hard (dried) fish
Harðfiskur, whole fillet |
Many kinds of fish dry well, but traditionally it is mostly cod, haddock and ocean catfish (wolf-fish) that are dried. Flounder also makes excellent harðfiskur, and in some areas of Iceland people also dry arctic char.
Drying haddock, cod and flounder:

Wash the fish and scrape off the slime, then gut the fish and remove the head. Haddock and cod can either be butterflied or filleted before drying. Flounder is filleted. If you butterfly the fish, you must take care to keep the fish spread open while it is drying.
To hang, cut a small slit through the flesh and skin of the tail end of the fillet, and thread a wooden dowel or a piece of string through it. The fish may be dipped briefly in brine before drying (recommended for flavour and prevention of spoilage during the drying process). Hang out to dry. To properly dry the fish, it should be done outside, in fairly cool (below 10 °C) and dry weather. The fish needs air movement to dry properly, and if it is windy, the wind will keep flies off the fish. Drying time depends on wind, air temperature and humidity.
Drying catfish/wolf-fish:
Ocean catfish (also known as wolf-fish), is fattier than cod or haddock, and needs to be dried faster to avoid spoilage. Fillet the fish and cut the fillet into two or four strips lengthwise, depending on size. Don't separate each two strips completely, but leave about an inch of the skin uncut. Cut the flesh into 1 1/2 cm. wide strips, taking care not to cut through the skin. Now you have what is known as riklingur in Icelandic. Hang on a wooden dowel and put out to dry. When it is dry, the riklingur can easily be cut into pieces with a pair of scissors, and the flesh can be easily torn from the skin. It is not necessary to beat this fish, unless it is so hard you worry about breaking your teeth on it!

Mass produced harðfiskur is made by fan or oven drying. It dries faster than wind-dried harðfiskur, and has a milder flavour.
There is a type of semi-dried fish called siginn fiskur, that has been allowed to hang for a few days until it has dried a bit and the flesh is firm like that of salt fish. It has a strong flavour and some would say it is spoiled, but it is still safe to eat. It is not nearly as pungent as cured skate, the traditional food eaten two days before Christmas.
Siginn fiskur, usually haddock or cod, is traditionally served with plain boiled potatoes and white (béchamel) sauce.
