Apply few drops of oil all over the dough.
Rest the dough for 2 hours after covering with some moist kitchen towel.
Take a ball size dough & make it round between your palms.
Dust some flour on surface & roll the dough into roti. You may shape it round or oval. Also this roti must neither be too thick nor too thin.
Apply water on one side of the rolled roti all over.
Put the wet side down on hot tawa. Make sure not to use non stick tawa & this tawa must be having an handle.
In couple of seconds, little bubble will be seen on the surface of roti.
