 Chashni or sugar syrup is used in many Indian sweets and desserts in varying consistencies such as one-thread, two-thread or three-thread consistency (1 tar-chasni, 2 tar-chasni or 3 tar-chasni).Its preparation involves boiling of water with sugar and stirring till the desired consistency is reached.For foods in which chashni needs to be absorbed, a thinner consistency called single thread syrup is used.
