Origin

The first record of the term rakfisk dates back to 1348, but the history of this food is probably even older. No sources are available as to the exact invention year of the rakfisk dish or the fermentation process that produces the raw material for it.

The rakfisk dish is related to the Swedish dish surströmming

, preferably over 750g. Remove the gills and guts and rinse well so that all the blood is gone. Scrub the blood stripe with a fish brush. Rinse the fish and put it in vinegar solution for about half an hour. Let the fish rest and the vinegar run off for a while. Then place the fish in a bucket, close side-by-side with the abdomen facing up. Fill the abdomen with sea salt (60g per kilogram of fish). Sprinkle tiny amounts of sugar on the fish to speed up the "raking", but not more than a pinch for each layer of fish.

Then place the fish under pressure with a lid that fits down into the bucket and a weight on top. The rakfisk bucket is put in a cold place (a stable temperature at about 4 degrees Celsius is the best, but it should be below 8 degrees Celsius at least). After a couple of days you should check if the fish is brined
Brining
In cooking, brining is a process similar to marination in which meat is soaked in brine before cooking.Brining makes cooked meat moister by hydrating the cells of its muscle tissue before cooking, via the process of osmosis, and by allowing the cells to hold on to the water while they are cooked,...

 containing 40g salt per litre of water. The fish may be placed at a higher temperature for some days to make it brine better, but one should be very careful with this.

Leave the rakfisk for two to three months. Rakfisk is well conserved in the brine. When the fish is appropriately "rak," you can put it into a fresh 4% salt brine, which will slow down the "raking" process. Another method for slowing it down is to put the tub in the freezer (or outside if cold enough) for some time. As long as the fish is lying in the brine it will not freeze.

Note that all recipes for rakfisk states that the fish must never be in contact with soil. This is very important because of the risk of the wrong bacteria
