The Korean term for food eaten while drinking, including yangnyeom chicken, is anju.
Anju is food consumed with alcoholic drinks in Korea. It can describe substantial dishes, small snacks, or shared plates ordered specifically to accompany beverages. Yangnyeom chicken—fried chicken coated in a sweet and spicy seasoned sauce—is a well-known modern example, especially when paired with beer.
The word should not be confused with banchan, the small side dishes served with a Korean meal. Jeon means a variety of pan-fried savory foods, while guk refers broadly to soup. Those are food categories, not the general term for food eaten alongside alcohol.
Anju is closely connected with Korean drinking culture and is especially associated with soju, beer, and social gatherings. The famous pairing of Korean fried chicken and beer is known as chimaek, a blend of “chicken” and “maekju,” the Korean word for beer. In that setting, the chicken functions as anju, while chimaek names the particular food-and-drink combination.
