Ingredients

Instructions

  1. Step 1: In a medium saucepan, combine 4 cups water, 10g dried kelp, and 10g dried bonito flakes. Bring to a gentle simmer over medium heat for 20 minutes, then remove from heat and strain through a fine-mesh sieve into a clean bowl, discarding solids.
  2. Step 2: Return the strained dashi to the saucepan and bring to a bare simmer over low heat (do not boil). Whisk in 3 tbsp white miso paste until fully dissolved, then add 14 oz firm tofu, cut into 1/2-inch cubes, and 2 tbsp rehydrated wakame seaweed.
  3. Step 3: Simmer gently for 3 minutes until the tofu is heated through and the flavors meld, then remove from heat. Stir in 1/4 cup sliced green onions and serve immediately while piping hot.
