Ingredients
  

  • 4 cups water
  • 6 inch Japanese kombu (dried kelp), rinsed about 15 cm
  • 1 oz bonito flakes, dried and shaved
  • 1 oz dried seaweed soaked in warm water and drained
  • 4 oz silken tofu cut into small pieces
  • 2 ½ to 3 tablespoons white miso paste
  • 1 tablespoon scallion chopped
  • mushrooms, noodles, or a poached egg optional additions

Instructions
 

  • Make the Dashi Broth
    Add 4 cups of water and kombu to a pot. Heat over medium until just before boiling. Remove kombu. Add bonito flakes and simmer for 5 minutes. Skim off any foam.
  • Strain and Reheat
    Strain broth using a fine mesh sieve or cheesecloth. Discard bonito flakes. Return clear broth to pot and bring to a gentle simmer.
  • Add Seaweed and Tofu
    Add soaked seaweed and cubed tofu to broth. Simmer for 3 minutes until tofu is heated through.
  • Stir in Miso
    Turn off heat. Mix a few spoonfuls of hot broth with miso paste in a bowl until smooth, then stir mixture back into the pot. Do not boil miso.
  • Top and Serve
    Ladle soup into bowls, top with chopped scallions, and serve immediately.

Notes

  • Always remove kombu before the water boils to avoid bitterness.
  •  Mix miso paste with hot broth in a bowl before adding to avoid clumps.
  •  Use silken tofu for softness, or medium tofu for a firmer texture.
  • A small pinch of seaweed goes a long way – it expands!
