Place the short ribs in a bowl with water and soak for an hour to draw out the blood.
While the beef soaks, chop the carrots into wedges and do the same to the radish.
For the sauce, combine the light soy sauce, mirin, sugar, garlic, ginger, black pepper, and soju, and mix thoroughly.
Drain the beef and give it one more rinse, then set aside.
In a pot of boiling water, blanch the short ribs for a few minutes. Drain the boiling water and rinse the ribs one more time.
In the same pot with no water, add the ribs along with the sauce and the 2 cups of water. Bring to a simmer, then cover and cook for about 20 minutes.
Add the carrots and radish, give everything a mix, and cover again for an hour.
After an hour, remove the lid and check that the meat is tender. Once it is, add the dried jujubes and put the lid back on for another 10 minutes before removing from the heat.
Spoon the galbi-jim into a bowl. Optionally garnish with sesame seeds. But it's your food, you eat it how you like.
