Gamjatang Recipe (Korean Pork Bone Soup with Potatoes)

About This Dish
This gamjatang serves two and needs about 1 hour of soaking before about 1 hour and 30 minutes on the stove. Meaty pork neck bones simmer until tender, then cook with potatoes and cabbage in a spicy broth seasoned with doenjang (Korean soybean paste), gochugaru (Korean chili flakes) and ground perilla seeds. The key is to simmer the bones until the meat comes off easily before the vegetables go in.
The name means “potato stew,” but the National Folk Museum of Korea’s encyclopedia notes several views on its origin and states that no records fix its first date or place. The Korean Cultural Center Association describes theories that connect the name to the pork spine or spinal cord rather than to the vegetable.
The Wtable recipe uses boiled siraegi (dried radish greens) or blanched young cabbage. This version uses blanched Korean cabbage leaves and finishes with kkaennip (perilla leaves).

Bring a pot of water to a boil. Add the bones. When the water boils again, boil for about 5 minutes. Drain the bones. Rinse them in cold water.
Put the bones and water in the large pot. Add the onion, garlic cloves, ginger, doenjang and the white part of 1 green onion. Bring it to a boil over high heat.

Skim off the foam. Cover the pot. Simmer over medium-low heat for about 60 minutes, until the meat comes off the bone easily.
Meanwhile, blanch the cabbage in boiling water for about 2 minutes. Rinse it in cold water. Squeeze out the water. Cut the cabbage into bite-size pieces.

- The broth boils throughout and covers the bones

FAQ
What bones should I buy?
Use pork neck bones or pork spine with plenty of meat attached. Korean grocery stores sell them, sometimes frozen. About 1 kg (2.2 lb) with bones serves two in this entry.
Why is my broth thin?
At step 7, cook with the lid off to reduce the broth. Taste it when the potatoes are soft, and adjust the seasoning.
How do I store leftover gamjatang?
Divide it into small, shallow containers and refrigerate within 2 hours after cooking (1 hour if the room is 32°C (90°F) or hotter). Keep it at 4°C (40°F) or below and use it within 3–4 days. Bring it to a full boil when you reheat it.
Does the name come from the potatoes?
It is not settled. The National Folk Museum of Korea's encyclopedia notes several views, and the Korean Cultural Center Association describes theories that link the name to the pork spine rather than to the potato.
