In a wide vessel, sieve both the flour and mix with salt and oil.
Slowly add milk (lukewarm milk) and mix with the flour to make a pliable dough. Add 1-2 tbsp of water as and when needed.
Cover it and keep it aside for 1 hour.
After an hour make equal portions of dough and make lemon-sized balls out of it.
Take out a ball and roll it into a small roti and spread a tsp of oil on this.
Dust some all-purpose flour over this. Alternatively, rice flour can also be used for this.
Roll one more ball into a small size roti.
Place this over the dusted roti like a sandwich.
Roll this into a thin roti and meanwhile heat a tawa.
The tawa should be very hot.
Transfer the thinly rolled roti to the tawa and immediately you can see bubbles forming on the roti.
Flip this and let the other side cook.
These actions should be quickly done, otherwise, they will get burnt and end up in crispy rotis.
When it is warm, slowly separate the two rotis. This can be easily done.
Fold it into triangles and do repeat the same procedure for the remaining dough.
Serve hot with any of your favorite side dish.
Though we had mixed vegetable curry, when I made this and was ready to click, I had some little dal makhani which I made in the morning, and clicked the pic with dal makhani!!.
