To get really soft chapatis, the trick lies in the kneading. The more you knead, the smoother the dough becomes and the smoother the dough is, the softer the Chapatis. Another secret to soft Chapatis is using fresh yoghurt or milk instead of water, to make the dough! When you're done kneading the dough and it is smooth, wet your hand with water and run it all over the surface of the ball of dough. Cover with a damp cloth and set aside for half an hour before using.
