Pickled herring

Pickled herring is a delicacy in Europe, and has become a part of Baltic, Nordic, Dutch, German, Eastern Slavic and Jewish cuisine. Most cured herring uses a two-step curing process. Initially, herring is cured with salt to extract water. The second stage involves removing the salt and adding flavorings, typically a vinegar, salt, sugar solution to which ingredients like peppercorn, bay leaves and raw onions are added. In recent years also other flavors have been added due to foreign influences. However, the tradition is strong in Denmark, Sweden, Finland, Norway, The Netherlands, Iceland and Germany. Onion, sherry, mustard and dill are some of the traditional flavourings.
