Labskaus

Labskaus isn't the most visually appealing dish, but it's a delectable mash-up that captures the northern German seafaring traditions like no other. Ship provisions were mostly preserved fare in the 18th and 19th centuries, and the pink slop of labskaus was a delicious way of preparing them.

Pickled gherkins and rollmops are served alongside salted beef, onions, potatoes, and pickled beetroot mashed up like porridge (see below). Sailors from the Baltic and North Sea have long favored it.
The dish is now popular throughout northern Germany, particularly in Bremen, Kiel, and Hamburg. Even though modern ships have refrigerators, it is still used as a hangover cure.
