Jangdok (Hangul:장독) means “a (big) jar” and dae (Hangul:대) means “place”, “support”… so jangdokdae (Hangul:장독대) means “place for jangdok(s)”. The jars are called hangari (Hangul:항아리) or onggi (Hangul:옹기).
This place is commonly found directly near traditional Korean houses, more precisely near the kitchen. Sunshine and ventilation are key aspects in the location choice, so that foods can be preserved and kept fresh. Well-preserved ingredients may stay for several years in the jars.
