Pickled herring is a popular delicacy in Europe, and has become a basic part of both Jewish and Nordic 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. Pickled herring is also common in Russian cuisine, where it can be served as simple as just cut into pieces seasoned with sunflower oil and onions, or can be part of herring salads, which are usually prepared with vegetables and seasoned with mayonnaise dressing. In the United States, pickled herring is often sold and consumed in a sour-cream based sauce, as well as in the more traditional wine- and vinegar-based marinades.
