Korean soup architecture — encompassing guk (broth soups), tang (rich stews), and jjigae (thick stews) — builds on a consistent foundation principle: the broth establishes the foundation umami, then a primary protein, then seasoning paste (doenjang or gochujang), then vegetables in sequence from densest to most delicate. The Korean soup palette prioritises a specific type of savoury depth produced by the combination of dried anchovy glutamates, fermented paste amino acids, and sesame oil volatiles.
- **Guk (thin soup):** Light broth with minimal seasoning — typically soy sauce-based. Consumed during the meal rather than as a separate course. - **Tang (rich soup/stew):** Gamjatang (pork neck and potato), seollongtang (ox bone soup cooked for 12 hours until milky white) — rich, gelatinous, typically long-cooked. - **Seollongtang technique:** Ox bones at a full rolling boil for 8–12 hours — the collagen converts to gelatin and the marrow fat emulsifies into the broth, producing the characteristic milky white colour. The boil (not a simmer) is specifically required for the colour — only vigorous boiling emulsifies the fat. - **The doenjang finishing:** Added at the end of cooking, not at the beginning — the prolonged heat degrades its complex amino acids. Added 10 minutes before service.
