Jinjuseong Haejangguk: The Fortress Hangover Soup

Jinjuseong Haejangguk (진주성해장국) is a variety of haejangguk — the Korean category of restorative soups traditionally consumed to cure hangovers or restore energy after hard labour — made by simmering pork spine bones (등뼈) with bean sprouts, dried radish greens, and perilla seeds in a deeply spiced chilli broth for several hours. The Jinju version is distinguished by its use of a secondary fermented paste base unique to South Gyeongsang Province, which gives the broth a sour-savoury complexity absent from most northern haejangguk variants. The soup has been served near Jinju Castle (진주성) continuously since at least the eighteenth century.

Jinju has been one of the most significant cities in South Gyeongsang Province for centuries, and its culinary traditions reflect both the sophistication of the local yangban (aristocratic) class and the practicality of a city that has withstood repeated military sieges — most famously the Battle of Jinju in 1592 during the Japanese invasions. Haejangguk near the fortress developed as sustenance for soldiers and market traders who gathered outside the castle walls, and the soup's restorative intensity reflects these utilitarian origins. The dish became famous beyond Jinju when Joseon-era travel writing described it as the finest haejangguk in the southern provinces.

The haejangguk restaurants near Jinju Fortress open from 5 AM and serve continuously until mid-afternoon. The dish is consumed in the context of a full Jinju food tour that typically includes bibimbap (Jinju is also famous for its own variation), yukhoe (raw beef), and cold noodles. The fortress itself, with its famous cliffside pavilion Chokseongnu, is a 5-minute walk from the haejangguk street.

The soup is intensely spicy by national standards — beginners should start with the mildest option. Order extra rice as the broth is best consumed with copious steamed rice. The fortress-side haejangguk restaurants are most atmospheric in early morning when steam rises from the pots and the castle walls are still in shadow.
