Jajangmyeon is a popular Korean-Chinese dish that originated in Incheon, South Korea. It was introduced by Chinese immigrants in the late 19th century and has since become a beloved comfort food in Korean cuisine.

In South Korea, Jajangmyeon is traditionally consumed on Black Day, a day for singles to celebrate by eating black-colored foods.
