Instructions

  1. Step 1: In a medium pot, bring 4 cups water to a gentle simmer. Stir in 1 tsp dashi granules until dissolved to create a flavorful broth base.
  2. Step 2: Place 3 tbsp white miso paste in a small bowl and ladle in about 1 cup of the hot broth. Whisk until the miso is fully dissolved and smooth.
  3. Step 3: Return the miso mixture to the pot, stirring gently to combine without boiling to preserve the miso's delicate flavor.
  4. Step 4: Add 7 oz soft tofu cut into 1/2-inch cubes and 1 tbsp dried wakame seaweed to the soup. Simmer gently for 3-4 minutes until the tofu is heated through and the wakame has rehydrated and softened.
  5. Step 5: Remove the pot from heat and stir in 2 tbsp fresh lemon juice to brighten the broth with a subtle sour edge.
  6. Step 6: Ladle the soup into bowls and garnish each with 2 thinly sliced scallions for a fresh contrast.
