Mandu-Guk — Dumpling Soup Shapes and Folds (만두국)

Mandu arrived in Korea from Central Asian dumpling traditions via the Mongol connections of the Goryeo period (13th century); the name derives from the Mongolian 'buuz'; Korean mandu has evolved distinct regional styles across seven centuries

Mandu-guk (만두국) is Korean dumpling soup — mandu (만두, filled dumplings) in a clear beef or anchovy broth, typically eaten on Lunar New Year. The shape of the mandu carries regional and cultural significance: the half-moon (반달 mandu) symbolises completeness; the pleated crescent (조각 mandu) signals northern Korean tradition; the round-purse style (둥근 mandu) of Gyeonggi province is the most common in Seoul. The filling — pork and tofu with kimchi and garlic chives or the plainer Kaesong style with pork and tofu only — determines the regional identity as strongly as the fold.

• Directly parallels Chinese jiaozi (饺子) and their soup counterpart wonton (馄饨), Japanese gyoza (餃子), and the broader Central and East Asian filled-dumpling-in-broth tradition — all originating from similar Mongolian/Chinese roots with regional adaptation

Mandu-guk for New Year is a ritual performance as much as a meal — the clear broth represents a fresh start; the dumpling represents wholeness and abundance. The shapes and the care in folding communicate the maker's respect for the occasion.
