Japanese Take-Out Miso Soup

1. 1

   To make the dashi: Line a strainer with cheesecloth and set it over a saucepan.

2. 2

   Wipe the surface of the kombu with a slightly damp kitchen towel, removing dirt and sand. Combine the kombu and 6 cups water in a pot over medium-low heat and bring to a simmer. Do not boil, as the kombu can become slimy and unpleasant.

3. 3

   Remove the kombu once it has risen to the surface. Immediately add the katsuobushi. After 10 seconds, remove the pot from the heat and skim off any foam. When the katsuobushi sinks to the bottom of the pot, pour the mixture through the cheesecloth into the saucepan.

4. 4

   To make miso soup: Soak the wakame in cold water for 5 minutes, then drain and set aside.

5. 5

   Bring 4 cups of the dashi to a boil over medium-high heat. Reserve the rest of the dashi for later use. Lower the heat, add the miso paste, and stir to dissolve. Add the tofu and bring to a simmer. Remove from the heat and add the green onion and wakame. Serve hot.

6. 6

   Make ahead: Dashi can be made up to 4 days ahead and kept covered in the refrigerator. It can also be frozen for up to 1 month.
