Siru

Siru (Korean: 시루) is an earthenware steamer used to steam grain or grain flour dishes such as tteok, most notably siru-tteok. The siru is an earthenware steaming vessel that dates back to the late bronze age of the Korean northern peninsula and the use of the utensil spread to the entire peninsula by the time of the Three Kingdoms in which the popularity of siru-tteok grew. The siru is also used during shamanic rituals and is even offered on the tables for daegamsin. The siru is not an everyday utensil but is one for preparing and serving the sacrificial dishes during rituals.
