Kongnamul-guk is a fixture of Korean home cooking: a clear broth built from nothing more than soybean sprouts, water, garlic, and scallion, often the meal that follows a late night out because it is light, not because of any particular effect. Cooks pass down one firm rule for it: never lift the lid while the sprouts simmer. Raw soybean sprouts carry a grassy edge from plant enzymes that turn volatile in hot water; trapped under a tight lid, that vapor has time to mellow into the broth's clean, faintly sweet flavor instead of venting into the kitchen and taking the flavor with it. Garlic, tamari, and a last-minute dusting of gochugaru are the only other ingredients doing real work, so the soup lives or dies on sprouts simmered whole and left alone.

Ingredients

Method

  1. Put the soybean sprouts, the white parts of the scallions, and 5 cups (1.2 L) water in a pot with a tight-fitting lid. Bring to a boil over high heat.
  2. Once it boils, cover and simmer for 8 to 10 minutes without lifting the lid. This is the one rule that matters here: every peek lets the sprouts' grassy volatiles escape before they have time to mellow into the broth.
  3. Lift the lid and check a sprout. It should have gone from squeaky-crisp to tender with a slight give. If it still squeaks, cover and simmer 2 minutes more.
  4. Add the garlic and simmer uncovered for 2 minutes, just long enough to lose its raw bite without turning bitter.
  5. Stir in the tamari, then taste. The broth should taste of the sprouts first and salt second; add more tamari a teaspoon at a time only if it needs it.
  6. Ladle into bowls and top each with the scallion greens, a pinch of gochugaru, and the toasted sesame seeds. Let each person stir their own gochugaru in at the table so they control their own heat.
