Tuna with Miso-Chile Sauce
This is a more complicated use of miso, useful not only for fish but for meat (just substitute tenderloin for the tuna). I learned it from Japanese-born chef Tadashi Ono, who now lives in New York. His dual lives encouraged Ono to take a few liberties of the type that few would take in Japan, with a classic sauce like this one; but if this is fusion cooking, it’s the good kind. The Japanese chili paste called tohbanjan is strictly traditional here, but you can use Vietnamese or Korean chili paste or simply cayenne. I love this with Basmati Rice with Shiso (page 510).
