Rotoli di mop

Rollmops is a German dish consisting of pickled herring fillets that are wrapped around ingredients such as gherkins, onion rings, or green olives. The combination is then usually skewered with a cocktail skewer. The dish is traditionally eaten cold, on its own or with bread. It grew in popularity in 19th-century Berlin, and it was a common pub food in the city. Aside from Germany, rollmops are also popular in England and Poland, especially during the Christmas season.
