Photograph has been taken at Kalna, Burddhaman,West Bengal,India. The villagers manufacturing the Gur. Khejur Gur (liquid date palm jaggery -- made from boiling the sap from date palms) is very popular in Bengal during the winter months. It is also commonly called "Notun Gur" ( literally, "new jaggery") or "Nolen Gur". I think the sap of the date palms is best during the winter months and that is the reason we get this gur or jaggery around this time.
