Each night of Ramadan, thousands of pilgrims come together to pray and break the fast at the holy shrine of Imam Reza, in Mashhad, Iran. It’s the world’s largest iftar, a meal eaten after sunset by Muslims observing Ramadan to break their daily fast. Cooking for such a crowd starts early and goes long. Over 400 volunteer chefs arrive at 5 a.m. to make culinary magic from 2 tons of fresh vegetables, 3 tons of meat and 4 tons of rice.
