What it is

Water pepper gave Japanese its proverb for taste, tade kuu mushi mo suki-zuki — there are even insects that eat water pepper — first recorded around 1600. The red sprouts sold as benitade are the same plant cut a few days after germination, when the pepperiness is at its sharpest and before any bitterness sets in.

In the kitchen

Pound the leaves with a little cooked rice and rice vinegar for tade-zu, the sauce for grilled ayu; the rice starch is what keeps it from separating on the plate. Scatter the sprouts at the last second — heat kills the pepperiness inside a minute.
