To begin with heat around 1 cup water in a pan to knead the dough.
Measure the rice flour and place in a wide bowl. To this add salt and oil. Now add required hot water and mix with a spoon. Cover the bowl and let it rest for about 10 minutes.
After that, knead the dough using you fingers and palm till soft and smooth. Now to make chapati/bhakri/flatbread first make euqal portions of dough.
Take a dough ball, flatten it with your fingers, dust some dry rice flour all over. Roll with a rolling pin gently.
If you are not able to roll then you may roll the dough between two plastic sheets.
Next heat tawa/ griddle, once hot place the rolled roti. Smear little water on top surface of roti with fingers or use a brush.
After a while, the top surface would start to dry, that means the down side is cooked well.
Now, flip roti and lower the flame to medium. Let it cook till you see few brown spots. Now with the help of tongs, roast both the sides directly over the gas flame.
Once done, serve immediately. You may apply ghee/butter, i haven't.
Similarly make rest of rotis, store them in cassarole or airtight container.
