1(8-ounce) block firm or silken tofucut into small cubes
2green onionsthinly sliced
1cupsliced mushrooms(shiitake or button work well)
1 to 2teaspoonssoy sauceto taste
Optional: 1 teaspoon grated fresh ginger or a pinch of ginger powder
Instructions
Add the water and kombu to a medium pot and heat over medium heat. Just before the water reaches a boil, remove and discard the kombu. Do not let it boil, as this can make it bitter.
Add the mushrooms to the pot and simmer for 3 to 4 minutes, until tender.
Lower the heat to low. Place the miso paste in a small bowl and whisk it with a few tablespoons of the hot broth until smooth.
Add the dissolved miso to the pot and gently stir to combine. Do not boil after adding the miso.
Add the tofu and cook gently for 2 to 3 minutes, just until heated through.
Stir in the green onions and soy sauce. Add ginger if using.
Taste and adjust seasoning as needed. Serve immediately.
Notes
Dissolve the miso: To prevent clumping in the soup and evenly disperse flavor. Do this in a separate bowl, a ladle, or use a strainer in the saucepan.
Never boil the soup: This is a big no-no for miso paste, affecting its flavor, potentially turning it grainy, and killing beneficial probiotic bacteria. It also makes kombu bitter.
Adjust the flavor: Taste and adjust. For a more robust flavor, add more miso paste (½ teaspoon at a time), mix miso types, and/or add dried mushrooms (or a mushroom blend).
