In Venezuela the Christmas dish consists of Hallacas (like tamales but more elaborate); Ensalada de Gallina (with potatoes, carrots and diced apples with mayonnaise); Pernil de Cerdo and Pan de Jamón.
The hallaca is the main part, and as such the tastiest and my favorite, both to eat it and to make it, which is not at all easy since it requires the help of the whole family.
Eating the same for several days is a universal Christmas tradition.
