Ingredients

Instructions

  1. Step 1: Place 5 g kombu in 4 cups cold water in a pot and let it steep for 15 minutes—do not boil, as this will make the dashi bitter.
  2. Step 2: Gently heat the pot over low heat until tiny bubbles form around the edges (about 80°C/176°F), then remove the kombu immediately to prevent bitterness.
  3. Step 3: Add 1 finely diced shallot and simmer for 5 minutes until fragrant and the shallot is translucent.
  4. Step 4: Stir in 3 tbsp white miso paste off-heat until fully dissolved, ensuring no boiling occurs to preserve the delicate flavor.
  5. Step 5: Rehydrate 10 g dried wakame in 1 cup warm water for 5 minutes, then add to the soup and heat through for 2 minutes until tender.
