This staple soup for centenarians is often cooked for breakfast and then reheated for lunch and dinner. It’s made distinctive with a base of richly fermented red miso and only takes about five minutes to make. Red miso is aged for a year or more—and as a fermented food, it provides the gut with beneficial bacteria.
2 cups dashi broth (page 105)
2 tablespoons red miso
3 tablespoons drained and crumbled firm tofu
1 cup Okinawan spinach (edible Gynura, can substitute with other spinach)
1⁄2 cup chopped green onion
Heat dashi broth to a low simmer.
Add all other ingredients, whisk until miso is dissolved, then simmer for 3 minutes.
Serve with rice.
