Ingredients

Instructions

  1. Step 1: In a medium saucepan, bring 4 cups of water to a gentle simmer over medium heat and whisk in 1 tbsp dashi granules until fully dissolved to create a clear, fragrant broth.
  2. Step 2: Add 1 tbsp dried wakame seaweed to the broth, allowing it to rehydrate and expand for 3 minutes until tender.
  3. Step 3: Lower heat to low and gently stir in 3 tbsp white miso paste using a small strainer or spoon, dissolving it completely without boiling to preserve its delicate flavors.
  4. Step 4: Carefully add 7 oz of silken tofu cut into 1/2-inch cubes, warming it gently for 2-3 minutes without stirring vigorously to avoid breaking the tofu.
  5. Step 5: Remove from heat and ladle the soup into bowls, garnishing each with 2 tbsp chopped green onions for a fresh bite and mild onion aroma.
