"Banh Chung" (Chung cake) is one of the most popular and delicious
traditional Vietnamese dishes. According to the legend, Chung cake was
invented by Prince Lang Lieu - the 18th Prince of Hung Emperor, in the
contest of looking for new Emperor. It has become an irreplaceable cake of
Vietnamese people at Tet and King Hung's anniversary (10th March of the
Lunar calendar).
Chung cake is made from sticky rice, pork, green beans, pepper and
onions. It is wrapped in dong leaves (lá dong). The cake will be boiled for
about 12 hours over a wood burning stove.
In Vietnam, the process of making Chung cake is the opportunity for family
to come together. All members in the family often make Chung cake together
