Pickling as a preservation method for fish has been around for over two millennia, and herring, being one of the most abundant fish in European waters, was an ideal candidate for pickling. The process of pickling, which involves immersing fish in a brine or vinegar solution, allowed people to preserve the catch for long periods, particularly in the colder months when fresh fish was scarce.

The earliest records of pickled fish date back to the time of the ancient Greeks and Romans. The Greeks were known to use vinegar and salt to preserve fish, and Roman texts suggest that pickled herring was a common foodstuff. The Romans also had a type of fermented fish sauce called garum, which was made from fish, including herring.  During the medieval period, pickled herring became essential for the European diet, especially in coastal regions and inland areas with limited access to fresh fish. The Hanseatic League, a medieval trade network of merchants in Northern Europe, played a key role in the spread of pickled herring trade, especially from the Netherlands, where herring fishing was a major industry.

Herring fishing and pickling became especially prominent in the Netherlands in the 15th and 16 century during the Dutch Golden Age.  Herring from the North Sea was abundant, and the Dutch perfected the art of preserving it by salting and pickling to export it to cities across Europe.  In the 1400s, Dutch fishermen discovered a method to "cure" herring by packing it in barrels with salt and vinegar, effectively preserving it for long voyages or storage. The Dutch developed the technique of "zout-haring" (salt herring), which involved using the fish's own brine and salt to preserve it.  The "New" Herring: The practice of pickling herring became so widespread that the beginning of each fishing season was marked by the arrival of the new herring, which was considered a delicacy. This was especially true in places like Amsterdam, where herring was not only a common food for the lower classes but also a symbol of prosperity and trade.

Over time, pickled herring became deeply ingrained in the culinary traditions of many Northern European cultures. It was particularly important in the Nordic countries, the Baltic states, and Germany.  In countries like Sweden, Denmark, and Norway, pickled herring (known as sill in Swedish) is a beloved part of the traditional holiday table. It is often served during holidays such as Midsummer, Christmas, and New Year’s Eve. Swedish pickled herring, or inlagd sill, is often flavored with ingredients like mustard, onions, and dill.  In Germany, herring is often served with onions, apples, and mustard, and in the Netherlands, it is commonly served raw or marinated and eaten with rye bread or on a bun. Dutch herring, also known as "Hollandse Nieuwe," is particularly famous. It is a type of herring that is eaten shortly after being caught, before it has been heavily salted or pickled. It is usually served raw and dipped in onions or eaten straight from the fishmonger's stall.

By the 19th century, with the development of refrigeration and other preservation techniques, the necessity of pickling fish for preservation decreased. However, pickled herring continued to be popular as a flavorful and nostalgic food.  European immigrants, particularly from Scandinavia, Germany, and the Netherlands, brought the tradition of eating pickled herring to America, especially to cities with large immigrant populations like New York. In the U.S., pickled herring became a common dish in Jewish delicatessens and is a part of Eastern European Jewish cuisine (particularly among Ashkenazi Jews), where it is often served as an appetizer with rye bread.  In the 20th century, the canning of pickled herring became widespread, making it more accessible around the world. Canned herring became popular not just as a snack but as a component of many ready-to-eat meals.

Today, pickled herring continues to be enjoyed in many parts of the world, from Scandinavia to Germany, and it remains an important part of traditional meals. Modern variations of pickled herring can be found in many supermarkets and gourmet shops, where it may come in different flavors, including spicy, sweet, or mustard-infused varieties.

Pickled herring has evolved from an essential preservation method to a beloved culinary tradition in many Northern European and Scandinavian cultures. Its history reflects the ingenuity of people in maritime regions, who turned abundant fish into a flavorful and lasting foodstuff. Whether served raw, marinated, or in sauces, pickled herring remains a testament to centuries of culinary tradition, offering a glimpse into the cultural importance of preserving food for long-term enjoyment.
