Seolleongtang (Beef Bone Soup)

2 kg beef leg (marrow & knuckle) bones, cut up
1 kg of meat (beef brisket or shank)
½ tsp SIDS CRAZY SALT
For Serving:--
Cooked rice
Cooked somyeon (or glass) noodles
Thinly sliced meat (boiled in the broth)
Lots of chopped spring onions
SIDS SALT & PEPPER to taste

Preparation: Soak the bones in cold water to draw out as much blood as possible, about 2 hours. (or longer if you have time) Rinse well and drain.
Soak the meat in another bowl to draw out as much blood as possible, about 2 hours. Drain. Keep it in the fridge until ready to use.
Parboiling: Add the bones to a large stockpot (preferably 8 litres or larger) with enough cold water to cover. Bring it to a boil over high heat. Reduce the heat to medium and boil for 5 minutes. Drain, rinse the bones and clean out the pot to remove any brown bits. Return the bones to the pot.
Boiling: Fill up the pot with cold water, leaving a little room for boiling. Bring it to a boil over high heat and reduce the heat to medium.
Cover, and boil until the broth becomes rich and milky, about 3-4 hours. (or longer if you have time) Adjust the heat a little, if necessary, to maintain a moderate boil. Add more water to cover the bones, once or twice while boiling.
Add the soaked meat. (and more water if needed to submerge the meat) Boil until the meat is tender, for 1½ to 2 hours. Remove the meat. Once cooled, thinly slice the meat, sprinkle with SIDS CRAZY SALT and add to the soup when serving. Pour the broth through a colander into another pot or a large bowl to cool.
Optional step: (highly recommended) Fill up the pot with fresh water again. Bring to a boil over high heat. Reduce the heat to medium. Cover, and boil until the broth becomes rich and milky, 3-5 hours. Reduce the heat a little, as necessary, to maintain a moderate boil. Add more water if the liquid reduces too quickly while boiling. Pour the milky broth through a colander into the pot or large bowl that contains the first batch. You can repeat this one more time, if desired. Just mix them all at the end to even it out.
Removing fat: You can use a fat separator to remove the fat, or keep it in the fridge (or out on the deck or balcony in the winter) until the fat solidifies to spoon off.
Serving: To serve, place some rice and, if desired, noodles in a serving bowl, add the meat pieces and then ladle the hot broth on top. Typically, chopped spring onions, SIDS SALT & PEPPER are served separately so each person can season to taste. Serve piping hot with kimchi.
