Add dashi in a pot and bring it to a simmeron medium-low heat.
Rinse the mushrooms thoroughly but quickly under running water, and discard the ends. Cut the tofu into small cubes.
Once dashi is boiling, add nameko mushrooms and cook for 2-3 minutes. Turn off the heat.
For the best result, add miso in the soup right before serving. Then add tofu and bring it to a simmer (not boiling).Turn off the heat and serve. Enjoy!
