Today at lunch I was reminded of what a special time of year this is. This gorgeous katakuchi bowl was presented with simmered octopus, fava beans, and fuki. Fuki is the stem of a bog rhubarb. It is no relation to the rhubarb I grew up with in Minnesota. It looks like a thin celery and has a somewhat similar texture, although more refined and elegant.
This time of year when sansai (mountain vegetables), like kogomi ferns, spring up from under the leaves that have covered the ground over winter. Angelica trees start to bud and the tender greens, tara no me, are harvested. And one of my favorites is the bitter butterbur, fuki no to, that is best when served as tempura. Some of these can be blanched and served with a splash of soy sauce.
If you are visiting Japan this spring, be sure to have a meal at a tempura restaurant that serves sansai. If you go out to an izakaya, ask them if they have any dishes with sansai. Some sansai are only around for a few weeks, so carpe diem.
