[1] Jang-jorim is a type of jorim, a Korean simmered dish that preserves well.
[2][3] The dish can also be made using shiitake mushrooms, quail eggs, and pork.
The first known description of jang-jorim is in Volume 128 of the Veritable Records of the Joseon Dynasty, where it describes a dish called damhae (Korean: 담해; Hanja: 醓醢) made by slicing beef and braising it in soy sauce.
[4] The dish is made by simmering small chunks of lean beef first in water, skimming off any scum.
Once the beef is cooked, the meat is simmered in soy sauce along with a mixture of garlic, ginger, and sugar.
