Mexican bakeries begin their preparations for Día de los Reyes Magos, or Three Kings Day, weeks before the holiday’s Jan. 6 arrival. At La Monarca Bakery & Cafe in Los Angeles, bakers have been mixing and freezing bread dough since early December for the celebration’s signature treat: rosca de reyes, or three kings bread.

For many Latinos, Three Kings Day concludes the holiday season. People line up outside their favorite bakeries early in the morning to pick up a rosca to celebrate the day the Magi brought gifts to the baby Jesus. Families gather later in the evening and eat the sweet bread along with champurrado, café de olla or hot chocolate.
