  • 4 dried shiitake mushrooms
  • 1 cup boiling water
  • 7 cups hot vegetable broth
  • 1 bunch green onions , chopped
  • 2 cloves garlic , minced
  • 1 tablespoon fresh ginger , minced
  • 1/2 pound firm tofu , sliced (optional)
  • 2 tablespoons rice wine (mirin)
  • 1/4 cup rice wine vinegar
  • 3 tablespoons tamari soy sauce
  • 1 or 2 jalapeño peppers , veins and seeds removed, minced
  • 2 teaspoons toasted sesame oil
  • Pinch of cayenne pepper
  • 2 tablespoons arrowroot or cornstarch
  • 1/4 cup cold water
  • 1/4 cup dark miso
  • 2 carrots , cut in matchstick slivers, or grated


  • Place the dried mushrooms in a bowl, pour the cup of boiling water over, cover, and let stand 10 minutes.
  • While the mushrooms are soaking, simmer the onions, garlic, and ginger in the vegetable broth for 5 minutes. Add the tofu (if using) and simmer 5 more minutes. Stir in the rice wine, vinegar, tamari, minced jalapeño, cayenne, and sesame oil.
  • Strain the soaking liquid from the dried mushrooms into the soup. Slice the mushrooms into slivers and add them.
  • Dissolve the arrowroot in the 1/4 cup of cold water. Add to the soup and bring to a gentle boil, stirring. The soup will become very slightly thickened.
  • Place the miso in a bowl and mash in 1/2 cup of the soup until smooth. Add the miso liquid to the soup along with the carrots. Heat but do not allow the soup to boil--boiling destroys some of the nutrition of the miso and changes the flavor. Taste the soup and adjust the seasoning with more vinegar, tamari, or cayenne, as needed. Serve immediately.
