Step 1

Make the dashi: Gently rinse the kombu piece. Place it in a medium pot with 4 cups water and gently simmer for 10 minutes. Don’t let it boil, or the kombu flavor will turn bitter. Once the kombu piece is soft, remove it and bring the water to a boil for just a few minutes.

Step 2

Reduce the heat again and add 1 cup more water. In a small bowl, stir the miso paste together with some of the hot dashi water (until it’s not clumpy), then stir to incorporate it into the soup broth.

Step 3

Add the ginger, scallions and shiitakes, turnips, and carrots and simmer on low until the turnips are soft and fork-tender (about 35-40 minutes). Note: If your soup is too thick, add 1-2 cups more water until it is a thinner consistency.

Step 4

Add the tofu and cooked soba noodles. Then taste and adjust seasonings, adding a few teaspoons of soy sauce if you like.

Step 5

Store leftover soup in the fridge for 3 to 4 days.
