I am making barbecued salmon for Sunday’s dinner. A traditional Japanese meal consists of a soup and three sides—the rice goes without saying—and this usually means miso soup. Miso soup can be as simple as dashi and miso, but frequently other ingredients are added to enrich this simple broth. Today, I am adding tofu—that I trimmed off my block of tofu for my salad—a few enoki mushrooms, and some wakami seaweed.
