Takuan

''Takuan'' (; also spelled ''takuwan''), or ''takuan-zuke'' (; 'pickled takuan'), known as ''danmuji'' () in the context of Korean cuisine, is a pickled preparation of daikon radish. As a popular part of traditional Japanese cuisine, ''takuan'' is often served uncooked alongside other types of ''tsukemono'' ('pickled things'). It is also enjoyed at the end of meals to aid digestion. Provided by Wikipedia
