# How-to Steps:

01 - Combine dashi stock, soy sauce, mirin, sesame oil, and salt in a large saucepan. Bring to a gentle simmer over medium heat.
02 - Add julienned carrots and sliced shiitake mushrooms to the simmering broth. Cook for 5 minutes until vegetables begin to soften.
03 - Add cubed tofu (if using) and simmer for another 2 minutes to heat through and absorb flavors.
04 - Place harusame noodles in a heatproof bowl and cover with boiling water. Soak for 4 to 5 minutes until tender. Drain thoroughly and divide among serving bowls.
05 - Add spinach or bok choy to the simmering broth and cook for 1 minute until just wilted but still vibrant.
06 - Ladle the hot broth and vegetables over the noodles in each serving bowl. Garnish with toasted sesame seeds and extra spring onion. Serve immediately while hot.

# Expert Pointers:

01 -
  • This soup comes together in under 30 minutes but tastes like something you simmered all day
  • The glass noodles soak up all that savory dashi flavor while staying delightfully springy
02 -
  • Do not boil the glass noodles directly in the soup or they will turn starchy and cloud your beautiful clear broth
  • The noodles continue absorbing liquid even in the bowl, so serve promptly for the best texture
03 -
  • Prep all your vegetables before starting since the cooking moves quickly once the broth is hot
  • Toasted sesame seeds make a huge difference so take the extra minute to toast them in a dry pan
