The Ajmer Sharif Dargah in Rajasthan, India, is one of the holiest Sufi sites in the world. There, devotees cook a sweet rice dish in a deg, or cauldron, for the thousands of pilgrims who visit the shrine each day. The cauldron is one of the largest in the world, measuring 37 feet wide and 15 feet deep, with a capacity to cook 4,800 kilograms. We visited the shrine to see how these devotees prepare their prasad, or religious offering, in such big batches.
