Rollmops

The word Rollmops, borrowed from Dutch (Originally: "rol 'm op" meaning "roll it") , refers to a pickled herring fillet rolled (hence the name) into a cylindrical shape around a piece of pickled cucumber or an onion. The whole thing is held together with one or two small wooden skewers. Rollmops are usually bought ready-to-eat, in jars. The marinade additionally contains water, white vinegar, salt, a bit of sugar or other sweetening agent, onion rings, peppercorns and mustard seeds. Rollmops can be eaten cold, without unrolling, or on bread. After the jar has been opened, rollmops will usually keep for 2-3 weeks if kept cool.

In the United States, pickled herring is often sold and consumed in a sour-cream based sauce, as well as in the more traditional wine- and vinegar-based marinades.

In Scottish cuisine, rollmop is a traditional snack food made of pickled herring combined with raw onions.

In Scotland the word rollmop refers to the configuration of the food, namely its distinct shape resembling a swiss roll.
