Ingredients Equipment Method Notes

Ingredients
  

Dashi
  • 4 cups 1 L cold water
  • 10 g kombu dried kelp
  • 15 g katsuobushi bonito flakes – omit for vegan
Soup Base
  • 3 –4 tbsp miso paste white = mild, red = bold
  • 1½ tbsp dried wakame seaweed
  • 2 –3 green onions thinly sliced
Flavor Add-Ins (pick 2–3)
  • 4 –6 fresh shiitake mushrooms thinly sliced
  • ½ cup enoki mushrooms
  • 1 small potato thinly sliced
  • ¼ cup shredded cabbage or baby spinach
  • 8 –10 small clams for asari miso
  • 1 sheet nori torn into pieces
  • 1 egg whisked (for egg-drop style)
Instant Dashi Option
  • 4 cups water + 1 tsp hon-dashi granules

Equipment

  • Medium saucepan
  • Fine mesh strainer
  • Small bowl + whisk (for dissolving miso)
  • Ladle

Method
 

  1. Make Dashi
  2. Cold water + wiped kombu → heat slowly → remove kombu just before boiling → add katsuobushi → steep 2–3 min → strain.
  3. Add Veggies
  4. Drop in mushrooms/potato/clams → simmer 3–4 min until tender.
  5. Rehydrate Wakame
  6. Soak wakame 5 min → drain → add to pot last minute.
  7. Dissolve Miso
  8. Ladle ½ cup hot broth into bowl → whisk miso smooth → pour back (never boil miso!).
  9. Finish
  10. Heat 30 seconds → ladle into bowls → top with green onions + any delicate extras.

Notes

No tofu = even lighter & lets dashi shine
Gluten-free → choose barley-free miso (most white miso is safe)
Vegan → skip bonito, add 2 dried shiitake with kombu
Make extra dashi → keeps 4 days in fridge
Never boil after adding miso → preserves flavor & probiotics
