You can put a couple of drops of sesame oil on it.
Horenso is spinach. I have never eaten or seen anybody eat raw spinach in Japan. We usually boil or steam it.
Spinach has rich Vitamin C and Iron, however, as you boil or put in the water, those nutritions will be reduced. Thus, you should not really boil long or put in the water long. Why then don’t I eat it raw? No, I don’t think it tastes good and is hard to eat.
Anyway, this is Horenso Goma-ae. Goma is sesame, ae means stir or mix.
After I boiled the spinach a short time and put it in cold water for a very short time, I strained them and squeezed out the water well, added seasoned soy sauce, ground sesame seeds, a pinch of salt and a pinch of mirin. Mix them well and serve.
It is easy, quick and a nutritious dish.
