Sesame Miso Soup

Why This Sesame Miso Soup Works

As the pot of water warms up, the miso paste and soy sauce spread through it and turn the plain water into a cloudy, salty broth. The miso has tiny bits of soybean that stay suspended in the water, so the soup feels a little thicker and smoother instead of thin like plain stock. Sesame oil floats across the top in a thin layer and clings to the miso, so each spoonful tastes full and rounded instead of watery.

Once the tofu and shiitake mushrooms go in, they sit in that hot miso broth and soak it up. The tofu stays soft but a bit bouncy, and the mushrooms loosen and become tender in just a few minutes. Near the end, green onions, nori, and sesame seeds only need a short time in the heat, so they keep some bite and texture. Grated ginger goes in right at the finish, so it stays bright and sharp and doesn’t fade into the background.

Mistakes To Avoid

Letting the soup boil hard after the miso goes in can make the broth turn cloudy and slightly grainy. The miso can separate into little bits instead of staying smooth, so the soup loses that silky feel and looks a bit curdled.

Adding the grated ginger at the very beginning with the water means it sits in hot liquid for too long. The ginger’s sharp edge fades and the soup can end up tasting flat and a little dull, instead of having a clean, bright finish at the end.

Throwing in the green onions too early and cooking them the whole time makes them go limp and tired. Instead of light, fresh pieces floating on top, they sink, lose their color, and the soup looks and feels more like it’s been reheated.

Cutting the tofu into very tiny pieces causes it to break apart while simmering. The cubes can crumble into the broth, so instead of soft, distinct bites of tofu, the soup gets a slightly murky look with tofu bits floating everywhere.
