Dongchimi
Dongchimi is a variety of kimchi consisting of Korean radish, napa cabbage, scallions, pickled green chilli, ginger, Korean pear and watery brine in Korean cuisine. As the name dong and chimi (hangul: 치미, an ancient term for kimchi), suggests, this kimchi is traditionally consumed during the winter season. Dongchimi is fermented like other varieties of kimchi, but its maturing period is relatively short (2–3 days). Although it can be made at any time of the year, it is usually made during the gimjang season. The northern regions consisting of Hamgyeong-do and Pyeongan-do in North Korea are particularly famous for their dongchimi.
