Gamja Tang: Pork Bone Soup

Gamja tang — pork spine and potato soup — is one of the great Korean long-simmered soups: a preparation where the collagen-rich pork spine bones are simmered for hours until the gelatine has enriched the broth, the meat is falling from the bone, and the doenjang-gochugaru seasoning has integrated completely. It is the Korean equivalent of French pot-au-feu or Vietnamese pho in its commitment to extracting maximum depth from bones over time.

Pork spine bones blanched, then simmered for 2–3 hours with doenjang, gochugaru, garlic, and aromatics. Potatoes added in the final 30 minutes. The result is a deeply rich, spicy, gelatinous broth with fall-from-the-bone meat.

Gamja tang is sustaining rather than refined — it is the soup that feeds through cold, exhaustion, and hunger. Its depth comes from patience: the hours of simmering that transform water and bones into something that coats the inside of a bowl. The spice is heat-forward rather than aromatic, warming the body as much as the liquid does.
