noun
salted rice-bran paste for pickling

noun
mashed green soybeans
A dish of boiled green soybeans (edamame) mashed into a coarse paste, sometimes seasoned. This sense is dialectal or old-fashioned; in modern Japanese, ずんだ (zunda) is the standard term.

In the Tohoku region, mochi with mashed green soybeans is enjoyed as a local specialty.
The exact derivation is uncertain. The kanji 糂汰 are ateji, and the word likely originated as a regional term for fermented bran paste or mashed beans, later replaced by more common synonyms.
