Naengmyeon has been made since the Joseon Dynasty. Originally a delicacy in northern Korea, especially in the cities of Pyongyang and Hamhung in North Korea, naengmyeon became widely popular throughout Korea after the Korean War. Naengmyeon is served in a large stainless-steel bowl with a tangy iced broth, julienned cucumbers, slices of Korean pear, thin, wide strips of lightly pickled radish, and either a boiled egg or slices of cold boiled beef or both. Spicy mustard sauce (or mustard oil) and vinegar are often added before consumption. Traditionally, the long noodles would be eaten without cutting, as they symbolized longevity of life and good health, but servers at restaurants usually ask if the noodles should be cut prior to eating, and use scissors to cut the noodles.
