Ingredients Method Notes

Ingredients
  

  • 3-4 lbs Leg bones / knuckle bones (사골) Usually sold frozen at Asian grocery stores
  • 3-4 lbs Marrow bones (우골) Usually sold frozen at Asian grocery stores
  • 1-2 lbs Beef flank Alternatively use 2-3 lbs beef brisket
Seasoning and garnishing
  • Salt to taste
  • Black pepper to taste
  • Chopped scallions for garnish

Method
 

  1. In a large bowl, add the bones and fill it with cold water. Enough to cover the bones. Cover and refrigerate overnight to draw out blood and impurities.
    3-4 lbs Leg bones / knuckle bones (사골), 3-4 lbs Marrow bones (우골)
  2. Strain out the water. Boil fresh water in a large pot, add the bones and beef flank or brisket, and bring to a boil. Simmer for 10-15 minutes until brown scum rises to the top
  3. Remove the beef and bones, carefully discard the hot water, and rinse the bones under cold water to remove any remaining scum. Use kitchen tongs or rubber gloves as the bones may be hot to touch.
    1-2 lbs Beef flank
  4. First simmer: Return the bones to a clean pot with fresh water and simmer for 2-4 hours (see notes for timing). Remove beef flank after ~45 minutes and brisket for ~2 hours, or when a chopstick easily pierces the meat.
  5. When cooled enough to handle, slice the meat thinly for serving and refrigerate until ready to eat
  6. Continue simmering the soup and skim any floating oil and add water as needed during the cooking time.
  7. Pour the first batch of soup into a large metal or heat-safe glass bowl to cool before storing in the refrigerator.
  8. Second simmer: Place bones back in the pot with fresh water and simmer for 4-8 hours (refer to notes for timing). Repeat the 1st batch steps: skim off oil, add more water, pour the second batch of soup to cool.
  9. Third simmer (optional): Repeat the second batch steps if desired (refer to notes for timing).
  10. After cooling overnight, remove any oil on top and combine all batches in a large pot and bring to a gentle simmer.
  11. Serve: Season the soup with salt, black pepper, and scallions. Serve with cooked rice and Korean radish kimchi.
    Salt to taste, Black pepper to taste, Chopped scallions for garnish
  12. Storage: The soup can be refrigerated for 2-3 days or frozen up to 2-3 months (refer to notes for thawing tips)
