Chueo

Chueo-tang or loach soup is a Korean tang (soup) that prominently features pond loach, a freshwater fish. The city of Namwon in southwestern South Korea is known for its version of the dish. Chueo (추어; 鰍魚) is a nickname for pond loach, called mikkuraji (미꾸라지) in Korean. Tang (탕; 湯) means soup. As irrigated rice paddies are drained after chubun (autumnal equinox), chubby pond loaches, ready for hibernation, are easily caught in the ditches dug around paddy fields. Chueo-tang (추어탕) is often a featured dish in banquets for the elderly.
