Bánh tét is a South Vietnamese specialty, a sticky rice cake that can be either savory or sweet. It is made from glutinous rice stuffed with a mung bean or pork filling and wrapped in a banana leaf. The whole concoction is then boiled or steamed, the banana leaf is removed, and the log-shaped cake is sliced into cylindrical pieces.
Banana leaves are used because they impart a unique aroma and flavor to the rice, reminiscent of tea. The cake will often be wrapped in plastic with a red or gold ribbon tied around it in order to make bánh tét look more festive, because it is traditionally prepared and served for the Vietnamese Lunar New Year celebration.
