Día de los Muertos (Day of the Dead) begins today and runs through Thursday (October 31-November 2). The Mexican holiday has its origins in Aztec rituals for honoring deceased ancestors, but has incorporated Christian traditions over time, including moving the dates to coincide with All Saint's Day, the same way Halloween has moved away from its Celtic origins. As far as celebrating Día de los Muertos, we are familiar with sugar skulls, but there are other foods associated with the holiday, like Pan De Muerto.
This traditional, sweet "bread of the dead" is one of the most important recipes for celebrating Día de los Muertos. It's made to look like a pile of bones and is brought along by families visiting the graves of their loved ones.
