About this dish

Sagol-guk is a Korean bone broth soup made by simmering beef marrow bones for six hours or longer until the dissolved collagen and marrow turn the liquid a dense, opaque white that looks closer to milk than water.

The seasoning is intentionally minimal, limited to green onion, garlic, and salt, because the entire point of the dish is the bone itself and what slow heat extracts from it over time. Before the long simmer begins, the bones are soaked in cold water to draw out the blood and then briefly blanched to remove any remaining impurities that would cloud or bitter the broth. The same bones can be reboiled three or four times, with each successive batch yielding a progressively lighter and cleaner-tasting liquid. The soup is served piping hot alongside rice, with salt and white pepper passed at the table so each person can season according to preference. Alongside seolleongtang and gomtang, sagol-guk forms one of the three pillars of Korea's long bone broth tradition, and its restorative reputation makes it a natural choice on cold days or when the body needs warmth and something uncomplicated.

Instructions

Read the steps as a cooking flow: prep, heat, seasoning, doneness control, and finish.

6 steps
  1. 1
    Finish

    Place 1000 g beef marrow bones in a large pot or bowl and cover fully with cold water.

    Soak for 2 to 3 hours, changing the water every 30 minutes so blood is drawn out and the finished broth tastes cleaner.

  2. 2
    Control

    Move the drained bones to boiling water and blanch over high heat for 10 minutes.

    Discard the blanching water completely, along with the foam and gray scum, because keeping it would make the broth muddy and heavy.

  3. 3
    Control

    Rinse each blanched bone under cold water, rubbing off any clinging bits, and rinse the pot as well.

    Return the clean bones to the clean pot, then add 3000 ml fresh water so the long simmer starts clear.

  4. 4
    Control

    Bring the pot to a strong boil over high heat, then skim off the first foam as it rises.

    Lower to medium low heat and keep the liquid gently moving, not violently boiling, so the broth extracts slowly without tasting harsh.

  5. 5
    Control

    Simmer for 6 to 8 hours, topping up with hot water whenever the level drops below the bones.

    The broth is ready when it turns milky white and feels slightly sticky on the lips from the extracted collagen.

  6. 6
    Season

    Season just before serving with 1 teaspoon salt, then taste and adjust at the table if needed.

    Slice 1 green onion diagonally, mince 4 garlic cloves, and add them over the very hot broth so their aroma stays fresh.
