Chajangmyeon is a popular Korean noodle dish made with thick wheat noodles topped with a savory black bean sauce. The sauce, known as chajang, is typically made from fermented black soybeans, diced pork, and various vegetables like onions and zucchini. This dish is often served with a side of pickled radish, adding a refreshing contrast to the rich flavors. Originating from Chinese cuisine, Chajangmyeon has become a staple in Korean food culture. It is commonly enjoyed as a comfort food and is often ordered for delivery. The dish is especially popular on Black Day, a day when singles in South Korea gather to eat Chajangmyeon to console themselves.
