I had this as a late-night snack in Japan, but it’s great at breakfast, too, a soothing, homey soup that is also good made with tofu or leftover chicken. Even if you don’t have dashi, you can execute this dish in a half hour or so. You can make fresh rice for this, of course, but if you use leftover rice—which is fine—heat it first; the microwave does a fine job of this. Some Japanese make small individual omelets for each bowl, but others use the easier, if somewhat odd, technique of cooking the egg in the soup, as here.
