In a plate knead the wheat flour with water little at a time to form soft dough.
Preheat a non-stick pan over medium heat.
Divide the dough into equal portions. Roll out each portion on a floured surface into a thin circle using rolling pin. Always roll on one side of the dough, do not turn the roti.
Be careful while putting the roti on the pan, dusted side should be at upper side of the pan and fry one side till you see bubbles.
Flip and cook the other side till you see brown spots. Turn and press with a spatula from all the sides till it puffs up.
As soon as it puffs up, take off from the heat.
