If you don't stir the nukadoko every day, it will get moldy.
I'm pickling cucumbers using the nukadoko I inherited from my grandmother.
Standard spelling using the common kanji 床 for 'bed'.
Alternate spelling using the less common kanji 糠 for 'rice bran'.
Compound of ぬか (rice bran) and 床 (bed, floor). The term literally means 'rice-bran bed', referring to the bed of fermented bran paste used for pickling.
