Boil for about 10 minutes, then add 2 tbsp of miso. Cut silken tofu into small cubes. Add enoki mushrooms to soup. Sprinkle some dehydrated wakame (a type of seaweed, “instant” is fine) and boil with for about 3 minutes. Dish soup into a bowl and put in the diced silken tofu and sprinkle with thinly sliced spring onion.
