Herring (Clupea harengus).
Herring fish have been caught around the world for many thousands of years. The most abundant species belong to the genus Clupea, there are about 200 species of various herring. They are found in the shallow, temperate waters of the North Pacific, also North Atlantic oceans, the Baltic Sea, and the west coast of South America.
In the Scandinavian and the Nordic region the Baltic Herrings were a very important food source along with the Herring and the sprats (Sprattus sprattus). Herring’s were salted in wooden drums for the coming winter, an oily fish similar to anchovies and sardines that could also be pickled, smoked and cooked as a casserole with potatoes, bacon and onions. Oily fish are a good source of vitamin A, D and the Omega 3. Oily fish and forage fish also can contain contaminants like mercury and dioxin.
Pickled herring also known as Bismarck herrings, it has been a delicacy in Europe for centuries.
The pickling of Baltic herrings is prepared usually in 3 stages: 1. Cleaning and gutting. 2. Soaked in salted pickle over night, drained and finally the third stage placing the herring filets into the final pickle that was briefly brought to boil containing vinegar with spices, onions, peppers and flavor giving vegetables.
The traditional preserving and cooking method of herring used basic ingredients at the time, salt for smoking with various wood types, e.g. apple tree or aspen.
For pickling the ingredients used were; white vinegar, onions, dill, peppers, spice, salt and maybe at better days red wine or sherry. As the food culture grew and experimented with ingredients from other cultures then spices, herbs and vegetables from other cultures got acceptance and became more widely used. The following recipe uses fennel, ginger and kafir lime for a broader flavor range. Enjoy.
