ingredients
1(3-inch) piece kombu (rinsed)
4cups water
3tablespoons dried wakame seaweed
1/4cup white miso paste (shiro miso recommended)
1/3cup green onions (chopped)
6ounces silken tofu (cubed)
tamari (to taste (optional, for serving))
Instructions
1
Gently rinse the kombu. Place it in a medium pot with 4 cups water. Simmer over low heat for 10 minutes. Do not boil—this can make the kombu bitter.
2
While the kombu simmers, soak the dried wakame in a small bowl of warm water for 5 minutes to rehydrate. It will expand significantly.
3
Remove and discard the kombu from the pot.
4
In a small bowl, ladle a bit of hot dashi broth and whisk in the white miso paste until smooth to create a slurry.
5
Stir the miso slurry back into the pot of dashi.
6
Drain the rehydrated wakame and add it to the soup along with the cubed silken tofu and chopped green onions.
7
Warm the soup over very low heat for 1–2 minutes. Do not boil—this preserves the probiotics in the miso.
8
Serve hot, with tamari added to taste if desired.

Probiotic tip: Never boil miso soup after adding miso—high heat kills beneficial bacteria.
Customize it: Add shiitake mushrooms, daikon, spinach, or cooked rice for a heartier meal.
Storage: Store without miso for up to 3 days; add fresh miso when reheating to preserve flavor and nutrients.
