Stir the batter every time before you pour it. This brings together all the heavy ingredients that settle down at the bottom of the vessel. Use a 1/2 cup or 1/3 cup measuring cup or a small bowl to pour the batter rather than a ladle. Pour it from a height and not very low to get that mesh texture. Begin pouring from outwards and then come inwards. Connect the mesh with additional batter wherever you feel it needs to be. However, do not pour at one spot multiple times. Also, do not try to spread it like regular dosa.
