Ingredients

Instructions

  1. Step 1: In a small saucepan, bring 4 cups dashi stock to a gentle simmer over medium-low heat—never boil, as it will destroy the delicate flavor. Remove from heat immediately once bubbles form at the edges.
  2. Step 2: Stir 3 tbsp white miso paste into a small bowl with 2 tbsp of the hot dashi stock until fully dissolved, then slowly pour this mixture back into the simmering dashi while stirring gently to prevent curdling.
  3. Step 3: Add 1/2 block cubed firm tofu and 1 tsp rehydrated wakame seaweed to the soup, simmering gently for 3 minutes until tofu is heated through. Stir in 2 tbsp thinly sliced green onions and 1/2 tsp sesame oil just before serving to preserve the aroma.
