The traditional food for Guatemalans at Christmas is tamales. They are basically corn "maza" stuffed with chicken, wrapped in a banana leaf and boiled. They are rather tasteless compared to the tamales we eat in the states. They are made much differently in Honduras and have more flavor - according to a Honduran Missionary.
The traditional drink is Ponche. Basically it includes cut up pieces of almost every fruit available, including pineapple, papaya, melon, and prunes. It also has orange juice, cinnamon, and more. All of it is boiled together, and it remains as a liquid with chunks of fruit in it. You can drink it warm or cold." Hmmmm, interesting!
