Bánh Chưng 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 an essential part of the Tết holiday, which celebrates the Lunar New Year in Vietnam. The preparation of Bánh Chưng involves soaking the rice and mung beans, cooking the pork, and then assembling the ingredients into a compact package. After boiling for several hours, the cake is cooled and served, often enjoyed with pickled vegetables. It represents family unity and respect for ancestors during the festive season.
