Ingredients for Soup:

  • 1 pound dried udon noodles (or use fresh or frozen, cooked udon)

  • 1 cup soft or medium tofu, cut in small cubes

  1. Make the broth: In a large pot, bring 8 cups water to a boil over high heat. Add scallion, dried mushrooms, seaweed (if using), ginger, garlic, fresh mushroom trimmings and salt. Reduce heat to a gentle simmer and cook for 20 minutes. Strain and set aside.
  2. Meanwhile, in a separate pot, cook udon noodles until al dente, then drain, rinse well with cold water, and keep at room temperature.
  3. In a soup pot, melt butter over medium-high heat and swirl to coat the bottom of the pot. Add leeks and sliced shiitake and cook, stirring, until softened, about 2 to 3 minutes. Add ginger, garlic, mirin, sesame oil and soy sauce and cook for 1 minute. Turn heat to high, add reserved broth and bring to a simmer.
  4. Add bok choy and reserved noodles and cook for 1 to 2 minutes, until greens are cooked and noodles are heated through. Gently stir in miso and tofu. Turn off heat.
  5. Using tongs, divide noodles among 4 to 6 bowls. Ladle hot soup over noodles. Sprinkle with scallions and serve. Pass togarashi
