About this dish

Fu no karashi-ae is a Buddhist vegetarian dish from the Reihoku area of Fukui.

Rehydrated square fu and salt-rubbed cucumber are dressed with vinegar, miso, sugar, and pungent Japanese mustard. Fu is not bran; it is a light, porous food made from wheat gluten, and once squeezed it readily absorbs the mustard vinegar miso. The dish has long been served at Hoonko, the major annual Jodo Shinshu observance, as well as funerals and memorial services, where fu and miso provide useful protein without meat or fish. Blooming the mustard before mixing preserves its sharp aroma, while a 30-minute rest leaves the cucumber crisp and the fu thoroughly seasoned.
