The richness of the broth comes from what’s basically an Asian version of soffrito, the Italian “starter paste” that flavors so many delicious soups and sauces. Whereas the Italian version is a mixture of sautéed celery, onions, garlic, bell peppers, and sometimes tomato paste, this version uses miso, onion, ginger, and garlic sautéed in toasty sesame oil until browned and caramelized. We opt for red miso here, the saltiest and most pungent kind. If you only have white miso on hand, it will work, too; you just might want to add a splash of soy sauce to deepen the flavor.

How to Make It

Step 1

Heat oil in a large saucepan over medium-high. Add miso, onion, and ginger; sauté 10 minutes or until browned and fragrant. Add garlic; sauté 2 minutes. Add 4 cups water, stock, and mushrooms. Bring to a boil.

Step 2

Carefully drop eggs into broth; reduce heat to medium. Simmer 7 minutes. Using a slotted spoon, transfer eggs to a bowl filled with ice water. Let stand 1 minute. Peel eggs.

Step 3

Add buckwheat and carrot to broth; increase heat to medium-high, and bring to a boil. Reduce heat to medium-low; simmer 15 minutes or until buckwheat is tender.

Step 4

Add bok choy and green onions; cook until tender, about 5 minutes. Stir in vinegar. Ladle soup evenly into 4 bowls. Cut eggs in half lengthwise; place 2 egg halves on each bowl of soup.
