Takuan

Takuan (沢庵?), also known as takuwan or takuan-zuke, is a popular traditional Japanese preserved vegetable. This pickle is made from daikon radish. In addition to being served alongside other types of tsukemono in traditional Japanese cuisine, takuan is also enjoyed at the end of meals as it is thought to aid digestion. In Korean it is known as danmuji (단무지) and is typically added to gimbap or served as a side dish in Korean Chinese cuisine.
