Mushroom Miso Soup

Step 1

Make the dashi: Put kombu, dried shiitakes, soy sauce, mirin, sake and sugar in a large soup pot. Add 6 cups cold water. Place over medium heat, allow the liquid to barely reach a boil, then reduce heat to low and let cook at a very slow simmer for about 30 minutes. Skim foam as necessary. Let cool to room temperature. Strain through a fine-mesh sieve and add salt to taste. (Dashi may be prepared up to 2 days in advance.)

Step 2

Put the sliced mushrooms in a bowl and drizzle with sesame oil and soy sauce. Add garlic and ginger and season with salt and pepper. Toss and let marinate for 10 minutes.

Step 3

Put dashi in a large soup pot over medium-high heat and bring to a simmer. Add mushroom mixture and cook gently for about 5 minutes, until the mushrooms are just tender.

Step 4

Remove 1/2 cup hot broth from pot and place in a small bowl. Stir in miso to dilute, then return miso-broth mixture to the pot. Taste and adjust seasoning. Once the miso has been added, do not let the soup boil.

Step 5

To serve, cut the tofu in half and place a 3-ounce chunk in each of two large bowls. Ladle 2 cups of hot soup over the tofu. Sprinkle with enoki mushroom tips, scallions, shiso, sunflower sprouts, nori, red pepper and toasted sesame seeds as desired.
