Naengmyeon is a symphony that harmonizes with the taste and appearance of the noodles, soup, and decor. Its representative work is the Pyongyang Naengmyeon.One major characteristic that distinguishes the Pyongyang Naengmyeon, a intangible national cultural heritage number 6 in North Korea, from that of the South is that its cooking style is directly influenced and determined by the North Korean leaders. North Korea advertises that Pyongyang Naengmyeon has been re-developed and blossomed under the leadership of its leaders, Kim Il-sung, Kim Jong il, and Kim Jong-un, heralding a new era of Pyongyang Naengmyeon, and that people have been blessed yet again with this dish the leaders have created.However, the detailed instructions on the recipe for Pyongyang Naengmyeon given by the leaders themselves are not properly reflected in reality. There are many differences between what the leaders want and what the North Korean people are actually facing.Not only is the noodles not pure buckwheat, but ordinary people eat Naengmyeon that does not contain buckwheat at all. It is common to use many sorts of spices, and synthetic flavoring matters are also used for soup. Even in the most authoritative cookbooks, the cooking methods for Pyongyang Naengmyeon differ from the instructions of the leaders, and there are differences in how to cook Pyongyang Naengmyeon between each other.There are also differences between Pyongyang Naengmyeon that is served in Seoul and in Pyongyang.Rather, the Pyongyang Naengmyeon in Seoul is closer to the Pyongyang Naengmyeon demanded by the North Korean leader. Food culture can be preserved when an economy that can secure sufficient ingredients such as buckwheat and meat is supported.Nevertheless, there is a general consensus as to how the dish should look and taste in order to harmonize and create a culinary symphony. As a representative of the national dish and national food culture, Pyongyang Naengmyeon will continue to carry the centrifugal force of change and the centripetal force of unity. In the process, a new Pyongyang Naengmyeon may be born as a new heritage of national culture.
