Jajangmyeon (자장면; 짜장면; jjajangmyeon), a Korean Chinese cuisine, is a noodle dish topped with a thick sauce made of chunjang (a salty black soybean paste when unheated), diced pork and vegetables, and sometimes also seafood. Jajang (alternately spelled jjajang), the name of the sauce when heated, is the Korean pronunciation of the Chinese characters 炸醬, which literally means "fried sauce." Myeon (also spelled myun) means "noodle", which is represented by the Chinese character 麵.
The dish originated from zhajiangmian (炸醬麵, literally "fried sauce noodles") in China's Shandong region.  Zhajiangmian was adapted in Korea to fit the Korean taste. The start of jajangmyeon can be traced back to the Joseon Dynasty. When the Joseon opened the Incheon port, many Chinese people from the Shandong region moved to a town in Incheon, which is now known as Incheon China Town. These people created Chinese restaurants and adapted the traditional Shandong food zhajiangmian in a way that Korean people could enjoy. It is rumored that in 1905 a Chinese restaurant named Gonghwacheun(공화춘), created jajangmyeon. However, it turned out that Gonghwacheun was the first registered business. At this time jajangmyeon was a cheap dish that the worker class enjoyed and was more similar to Shandong region’s zhajiangmian than the current day Korean jajamyeon. After the Korean War, Korean chunjang was invented. With Korean chunjang, caramel was added to give it a sweet taste. After this jajangmyeon became a completely different food from zhajiangmian. The pronunciation of the dish's name is nearly identical to that of its Korean counterpart. But Korean jajangmyeon differs from Chinese zhajiangmian, as Korean jjajangmyeon uses black Korean chunjang including caramel, and onions.
Jajangmyeon uses thick noodles made from white wheat flour. The noodles, which are made entirely by hand and not by machines, are called sutamyeon (수타면; 手打麵) are praised in South Korea as an essential ingredient of good jajangmyeon.
While in Beijing cuisine, yellow soybean paste (黃醬) is used, in Tianjin and other parts of China tianmianjiang (甜麵醬), hoisin sauce (海鮮醬), or broad (fava) bean sauce (荳瓣醬) may be used in place of the yellow soybean paste. However, In Korea, the sauce is made with a dark soybean paste. This paste, which is made from roasted soybeans and caramel, is called chunjang (literally "spring paste", hangul: 춘장; Chinese: 春醬) when unheated, while the heated sauce (containing vegetables and meat or seafood) is called jjajang (literally "fried sauce"). Chunjang is stir-fried with diced onions, ground meat (either beef or pork) or chopped seafood, and other ingredients. The meat stock is added to reduce the salty taste, and potato starch or cornstarch is added to give the sauce a thick consistency. The sauce is served hot over noodles, sometimes with sliced raw cucumbers. The same sauce is also used to make jajangbap (rice served with the sauce) and jajangtteokbokki (tteokbokki made with the sauce instead of the usual spicy sauce).
Jajangmyeon is usually served with a small amount of danmuji (단무지). The dish is often served with a small amount of sliced raw onions, seasoned with rice vinegar, accompanied with a little chunjang sauce. The diner eats the noodle with danmuji and onions dipped in chunjang sauce.
Variations of the jajangmyeon dish include ganjajangmyeon (간자장면), which is jajangmyeon served with the jajang sauce without the starch, with the sauce and noodles being served separately in different bowls, and samseon jajangmyeon (삼선자장면; 三鮮炸醬麵), which incorporates seafood such as squid, shrimp, sea cucumber, and others (but never fish). Samseon ganjajangmyeon (삼선간자장면; 三鮮간炸醬麵) consists of noodles served with sauce, which contains seafood on the side. Jajangbap is essentially the same dish as jajangmyeon, but made with rice instead of noodles.
Instant jajangmyeon consists of dried noodles that are boiled in the same manner as instant ramen with dried vegetable bits, drained, and mixed with jajang powder and a small amount of water and oil.
The dish has been known in South Korea as jjajangmyeon (or chajangmyeon; 짜장면) since the first time the dish was imported to Korea. Even in current times, the vast majority of Korean Chinese restaurants use this Korean spelling.
However, according to Korean Alphabetization of Foreign Words (외래어 표기법; 外來語 標記法), a manual under a regulation issued by South Korea's Ministry of Culture and Education (문화교육부; 文化敎育部) (currently the Ministry of Education, Science and Technology (교육과학기술부; 敎育科學技術部)) in 1986, the Korean alphabetization of stop consonants (e.g. 짜; jja; Cha) should not use Korean fortis except for some established usages. According to this rule, the Korean alphabetization of the word '짜장면' is jajangmyeon. As a result, the alphabetization of the dish in recent years has been jajangmyeon in official government documents and the mainstream media.
However, there has been noticeable criticism on the Korean alphabetization of this word. Those in favor of the alphabetization jjajangmyeon question if champon should really be called Jambong as per the official manual (the popular dish was allowed to be alphabetized jjambbong as an exception to the rule). According to the 95th episode of Korean food culture cartoon Sikgaek (식객; 食客), Ahn Dohyeon (안도현), the So-wol Prize winning Korean poet, announced that he would always write the dish's name as '짜장면,' not '자장면,' because the former is the name with which he associates all his childhood memories of the dish.
Also, in most old Korean dictionaries, the hanja for jajangmyeon is "酢醬麵". The first hanja's Mandarin Chinese pronunciation is similar to 'ja', and the Mandarin Chinese pronunciation of the hanja "炸" is close to 'jja'.
On August 31, 2011, the National Institute of The Korean Language (국립국어원; 國立國語院) announced that jjajangmyeon (짜장면) has been accepted as an alternate standard spelling of the dish alongside the existing jajangmyeon (자장면) on August 22, 2011, and has been added to the Standard Korean Language Dictionary (표준국어대사전; 標準國語大辭典) with 38 other words, hoping to end the long-standing discrepancy between the commonly used spelling and the standard spelling.
