Tororo Soba
This summer recipe centers on a versatile ingredient that’s beloved in Japan but almost unknown here, one that I know you’ll enjoy. It’s called yamaimo, or mountain yam. This root has a nice, fresh taste, with a delicately sweet, nutty flavor and lots of umami, or sense of savoriness. The most popular variety, which you can find in Asian markets, looks like a tan-colored baton. Peel the skin and grate its white flesh. Raw yamaimo has a liquidy, slippery texture that might take getting used to, but it pairs beautifully with the toothsome soba in this dish. I’ve also added okra, a cooling Southern favorite that’s very popular in Japan.
