What it is

Rice bran only became abundant in the seventeenth century, when milling started stripping brown rice white — and beriberi, the thiamine deficiency, grew so common in the capital that it was called the Edo disease. The bran bed put the vitamin back: a cucumber left twelve hours in a nukadoko comes out with roughly ten times the thiamine it went in with.

In the kitchen

The bed is alive and wants turning by hand once a day, right down to the bottom, or it goes anaerobic and smells of solvent. Hold it around 12 percent salt by weight of bran, and when it turns watery bury a folded cloth or a handful of dried shiitake to draw the liquid out.
