While holiday traditions vary from place to place, food always plays an important role. The sweet, rich, glazed egg bread, Pan de Muerto, is always served, though it, too, varies in shape and decoration from region to region. The most common shape is round decorated with small pieces of dough on top that represent bones and skulls. Loaves in the shapes of human beings and animals—particularly rabbits—are also popular. White, colored or powdered sugar is often sprinkled on top of the loaves for a festive touch.
