Think of this comforting soup as a cross between ramen and miso soup. The broth gets instant depth from the bacon drippings in the pan, as well as the miso paste and shiitake mushrooms.
You’ll find white miso paste at most supermarkets, either in the refrigerated soy product section or on the international foods aisle. Use it to enrich broths, marinades, or salad dressings, keeping in mind that a little goes a long way.
Give the eggs a quick rinse in their shells since they’ll simmer directly in the broth.
