Banh Chung is a traditional Vietnamese rice cake made from glutinous rice, mung beans, and pork. It is square-shaped, symbolizing the Earth, and is typically wrapped in banana leaves before being boiled. This dish is commonly prepared during the Tet holiday, which celebrates the Lunar New Year in Vietnam. The preparation of Banh Chung involves soaking the rice and mung beans, cooking the pork, and then assembling the ingredients into layers. After wrapping the cake tightly, it is boiled for several hours. Once cooked, Banh Chung is often served with pickled vegetables and is a beloved part of Vietnamese culture and cuisine.
