Tet is the biggest festival in Vietnam. To celebrate Tet, Vietnamese people make many tasty traditional foods. The most important food includes Chung cakes, sausages, boiled chicken, spring rolls, and sticky rice. Chung cake is made of sticky rice, pork, green beans, and other spices, wrapped in green leaves, therefore this cake needs a lot of preparation. This cake can be kept for a long time, even though the weather is often humid during Tet. Other significant foods that cannot be missed to worship the ancestors are sausages, spring rolls, and sticky rice. Because sausages are difficult to make, people often buy them from famous suppliers. However, sticky rice and spring rolls are easier to prepare and must be served immediately after they are cooked, so they are often made at home.
