Tsukemono pickles

Tsukemono (漬物, literally "pickled things") are Japanese preserved vegetables (usually pickled in salt, brine,[1] or a bed of rice bran).[2] They are served with rice as an okazu (side dish), with drinks as an otsumami (snack), as an accompaniment to or garnish for meals, and as a course in the kaiseki portion of a Japanese tea ceremony.
