Instructions
- Step 1: Place 10g kombu in 400ml cold water in a small pot. Bring to just below simmer (160°F/70°C) over medium-low heat—do not boil, as boiling destroys the delicate flavor; steam will rise after about 5 minutes.
- Step 2: Remove kombu immediately once steam rises, then add 100g cubed soft tofu. Simmer gently for 3 minutes until tofu is heated through.
- Step 3: Stir in 1 tsp white miso paste until fully dissolved, then garnish with 2 thinly sliced scallions.
