Karupatti – Tamil Nadu’s own sweetener – is made from “padani” or sweet sap from the palm trees. The making of karupatti is still done in traditional ways across Tamil Nadu. Padani is collected from the palm tree in an earthen pot by the palm tree climbers. To avoid fermentation of the sap, the pots are coated with slaked lime. The sap from the palm trees is then filtered and boiled in a huge vessel for nearly five hours and turned into thick and viscous syrup. This syrup is then poured into coconut shells to give karupatti its unique shape.
