A light dashi broth made from kombu and bonito flakes, seasoned with miso and filled with silken tofu, wakame and spring onion.

Method

  1. 1

    Wipe the kombu with a damp cloth, leaving the white powder on the surface, since that carries much of the flavour.

  2. 2

    Put the kombu and the water in the saucepan and leave to soak.

  3. 3

    Set the pan over medium-low heat and warm it slowly until small bubbles form around the edge.

  4. 4

    Lift out the kombu just before the water boils, as boiling it makes the broth slimy and bitter.

  5. 5

    Turn up the heat and bring the water to a full boil.

  6. 6

    Scatter in the bonito flakes, turn off the heat and leave them to steep until they sink.

  7. 7

    Meanwhile, cover the wakame with cold water in a small bowl and leave it to soften.

  8. 8

    Pour the broth through a fine sieve into a heatproof bowl without pressing the flakes, then pour the dashi back into the rinsed pan.

  9. 9

    Drain the wakame, add it to the dashi with the tofu and warm through over low heat.

  10. 10

    Put the miso in a ladle, lower it into the broth and stir with chopsticks until it has dissolved.

  11. 11

    Heat until the soup is steaming but not boiling, since boiling dulls the aroma of the miso.

  12. 12

    Ladle into bowls, scatter with the spring onion and serve straight away.

Notes

  • Miso varies a lot in saltiness. Stir in two thirds of it first, taste, then add the rest if needed.
  • For a vegan version, soak 3 dried shiitake mushrooms with the kombu and leave out the bonito flakes.
  • The dashi keeps for 3 days in the fridge. Add the miso only when you reheat it.
