Pickled herring

A very popular scandinavian food item, pickled herring has been around for a very, very long time. In preparation herring are cut into filets and placed in a vinegar/salt/sugar solution to which peppercorn, bay leaves and raw onions are added. Once the pickling process is finished they are usually enjoyed on a dark rye bread slice. Another way to eat pickled herring would be as a roll-mop in which the herring is wrapped around a piece of pickled cucumber and then skewered with a toothpick.
