Jangeo-tang

A rich, stamina-boosting soup of freshwater eel (jangeo) simmered with medicinal herbs, gochugaru, and perilla seeds.

Jangeo-tang is one of Korea's designated stamina soups — a dish consumed deliberately for its perceived health benefits rather than casual eating. Freshwater eel (jangeo) has been valued in Korean traditional medicine for centuries as a source of high-quality protein, healthy fat, and vitamins that restore energy and virility, particularly during the three hottest days of the Korean lunar calendar (sambok), when Koreans traditionally eat strengthening foods to combat summer fatigue. The eel is cut into sections, briefly marinated in soy sauce and garlic, and simmered in a broth seasoned with gochugaru, perilla seeds (deulkkae), and ginger, which together create a peppery, slightly nutty, rich soup quite unlike any other in the Korean repertoire. The perilla seed flavour in particular — earthy, slightly smoky, resembling toasted sesame but more herbal — distinguishes jangeo-tang from other spiced meat soups. Restaurants specialising in jangeo-tang can be found near rivers and freshwater fish farms across Korea, particularly along the Seomjin River in South Jeolla Province and in the regions of North Chungcheong Province, where eel farming is a major industry. The soup is not everyday eating but a deliberate, seasonal investment in one's body.
