Sursild is a Norwegian pickled fish delicacy that is traditionally consumed during the winter holiday season, particularly on Christmas. The dish is usually made by combining slices of salted herring, onion slices, and a variety of spices such as allspice, black peppercorns, and mustard seeds in a jar, which is then filled with a boiled vinegar-based mixture.

A common breakfast meal, the pickled fish is usually consumed with slices of fresh bread, smeared with butter, and topped with onion slices, or with a side of boiled potatoes as a part of a large dinner. In Norway, jars of pre-made pickled herrings are also sold in numerous supermarkets in the country.
