In a medium saucepan, gently heat the Kombu Dashi or water until it is steaming. It's important not to let it come to a rolling boil, as this can affect the delicate flavor of the miso.

Reduce the heat to low. Ladle about 1/2 cup (480 ml) of the warm liquid into a small bowl and add the miso paste.

Whisk vigorously until the paste is completely dissolved and the mixture is smooth. This step prevents clumps of miso in your final soup.

Pour the dissolved miso mixture back into the saucepan. Gently stir in the cubed silken tofu. Allow the soup to sit over the low heat for a minute or two, just long enough to warm the tofu through.

Ladle the soup into bowls, garnish with the fresh minced scallions, and serve immediately.

Add a handful of tender greens like spinach or baby bok choy in the last minute of cooking for extra nutrients and a pop of color.

Garnish with a pinch of shichimi togarashi (Japanese seven-spice blend) or freshly grated ginger for a zesty, warming kick.
