The Morning Guk & Bap: Everyday Breakfasts

A heavy fistful of yellow-headed soybean sprouts, a handful of dried anchovy and dashima, and twenty minutes on the back burner. Together, they yield the earthy, nutty steam rising from a pot of kongnamul-guk. As the broth hisses, it offers something simple and restorative before facing the day. The secret isn't a long, arduous simmer—it's respecting the whole sprout and adhering to a strict, unyielding lid protocol. Lift the cover too early, and the sprouts taste raw and grassy. Follow the rules, and you unlock a bowl of bright, clear soup. Ladle the broth over the rice while it is still scalding.

Before you start

  • Pick through the soybean sprouts and leave the roots entirely intact.

    Submerge the sprouts in a large bowl of cold water, gently swishing to allow any loose husks to float to the surface. Skim off the debris and discard any mushy sprouts, but absolutely do not pinch off the tails; those long roots contain the essential amino acids and the deepest flavor.

Ingredients

  • soybean sprouts10 oz
  • water6 cup
  • Korean broth coins2 med
  • garlic1 tbsp
  • Korean salted fermented shrimp1 tbsp
  • Korean soup soy sauce1/2 tbsp
  • scallion1 med
  • jalapeno pepper1 small
  • kosher salt1/4 tsp

Method

  1. 01

    Build the foundational broth in a rapid boil.

    In a medium pot, bring the water to a rolling, aggressive boil. Drop in the broth coins and let them dissolve for three to five minutes to establish a rich, savory anchovy and kelp base.

  2. 02

    Add the sprouts and leave the lid completely off.

    This is the cardinal rule of kongnamul-guk. Soybean sprouts contain an enzyme that produces a foul, fishy odor if the temperature fluctuates. By cooking them uncovered in a continuous boil, those volatile compounds evaporate instantly. Boil uncovered for exactly three to four minutes.

  3. 03

    Season the soup in the final minute of cooking.

    Do not salt early, or the osmosis will draw moisture out of the sprouts and render them tough and stringy. At the three-minute mark, stir in the minced garlic, salted fermented shrimp, and soup soy sauce. Taste the broth and adjust with a pinch of kosher salt if necessary.

  4. 04

    Garnish with fresh aromatics off the heat.

    Turn off the stove and immediately stir in the chopped scallion and sliced jalapeno. The residual heat will take the raw edge off the aromatics without turning them to mush. Serve immediately with a bowl of warm rice.

Notes

  • Do not mistake mung bean sprouts for soybean sprouts.

    They might look similar to a novice, but mung bean sprouts lack the firm, yellow head of the soybean and will completely disintegrate into mush if boiled for soup.

  • Embrace the modern miracle of broth coins.

    No grandmother will judge you for using freeze-dried anchovy and kelp tablets on a Tuesday night. They compress twenty minutes of traditional stock-making into three minutes, perfectly suited for an American weeknight.

  • Turn up the heat for a spicy variation.

    If you want the sweat-inducing version often used to banish a cold, bloom a tablespoon of gochugaru (Korean chili flakes) into the broth along with the garlic.
