Instructions

  1. Step 1: Place 120g kombu in 1 liter cold water in a pot and let sit for 30 minutes to draw out flavor. Heat gently over medium-low until just before boiling (around 80°C), then remove kombu immediately to prevent bitterness.
  2. Step 2: Add 30g dried bonito flakes to the pot, bring to a gentle simmer for 2 minutes, then strain through a fine-mesh sieve into a clean bowl, discarding solids.
  3. Step 3: Cut 350g silken tofu into 1-inch cubes and set aside. Thinly slice 4 stalks shinji, reserving 2 tablespoons for garnish.
  4. Step 4: Return the strained dashi to the pot and add 2 cups vegetable stock. Bring to a bare simmer (do not boil), then add 4 tbsp miso paste, stirring gently until fully dissolved.
  5. Step 5: Add 20g rehydrated wakame seaweed and 1/3 of the tofu cubes, cooking for 3 minutes until the seaweed softens. Gently fold in remaining tofu and reserved shinji, cooking for 1 more minute until greens are bright green.
