Labskaus is a dish from northern Germany consisting of corned beef, mashed potatoes, and beets, with additional ingredients such as fried eggs, pickles, and rollmops—a pickled, rolled herring. Although its origins are somewhat murky, the dish was most probably invented in the 16th century, when it was typically eaten by poor people, sailors, and seamen, due to the fact that pickled and canned foods were inexpensive and could last during long travels.
