takuan, pickled daikon radish
A type of Japanese pickle made from daikon radish that has been sun-dried and then pickled in rice bran and salt. Characterized by its yellow color and crunchy texture.
Cultural note
Named after the Zen Buddhist monk 沢庵宗彭 (1573-1645), who is traditionally credited with popularizing this pickling method. 沢庵 is one of the most common 漬物 (pickles) in Japan, typically served as a side dish with rice. The bright yellow color comes from rice bran (糠) fermentation or sometimes from turmeric.
Also written in hiragana as たくあん or katakana as タクアン.
