Re: Inedible foods.
I do have another suggestion for you, another Norwegian dish that you really would not like to go near, it stinks, so here it is and the cooking method just in case anyone would like to try it.
LUTEFISK,
Lutefisk is made from dried whitefish (normally cod in Norway, but ling is also used) prepared with lye in a sequence of particular treatments. The watering steps of these treatments differ slightly for salted/dried whitefish because of its high salt content.
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 swells during this soaking, and its protein content decreases by more than 50 percent producing a jelly-like consistency. When this treatment is finished, the fish (saturated with lye) is 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.
After the preparation, the lutefisk is saturated with water and must therefore be cooked carefully so that it does not fall into pieces.
To create a firm consistency in lutefisk, it is common to spread a layer of salt over the fish half an hour before it is cooked. This will "release" some of the water in the fish meat. The salt must be rinsed off before cooking.
There are several ways to cook lutefisk:
Lutefisk does not need 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. An alternative is to wrap in aluminium foil and bake 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 falls apart. Prepare a white sauce to serve over the lutefisk.
