Marinated Herring with Juniper Berries and Bay Leaf

Why this dish? Herring preservation made the fortune of the Hanse, to which Toruń and the cities of Warmia belonged. A prudent canon kept his supply of marinated fish to get through the long fast days of the Baltic winter.

Zapasy — stored provisions, fish potted for keeping

Desalted herring marinated in vinegar with onion, juniper berries, bay leaf and peppercorns. Tangy, aromatic, it keeps for several weeks in a cool place.

Foresight, you see, is as valuable in cooking as in astronomy: one must know what is coming. Before winter closes the lagoon, I have the herring potted in vinegar, with onion, bay, and those little juniper berries that our forests give in abundance. The fish softens, takes a most agreeable sour edge, and lasts until Lent without spoiling. Thus the wise man fills his cellar as the heavens fill their spheres: with measure and constancy.
Nicolas Copernicus

How it was made : Brine-curing and then vinegar pickling were key techniques of the Hanseatic herring trade, which allowed Baltic fish to be transported far inland. Juniper, abundant in the north, served both as a flavoring and as a reputed antiseptic agent.
