Natto has diehard fans, but some people cannot get past the thick whipped-up threads surrounding the beans. Here, the natto is not aerated, and the spicy wetness of grated daikon helps mitigate the fermented funkiness, rendering the dish much more widely appealing and a tasty, healthy bite to start the day.
Try to source natto made locally rather than in Japan; imported natto is typically frozen for shipping and loses some of its unusual delicacy. (We like the New York-make NYrture brand—look for it in local specialty stores or online.) Konbu dashi is easy to make from scratch, and a batch can be used to make a variety of vegetarian Japanese dishes.
