Bring the water, oil and salt to a boil in a medium saucepan.When the water just begins to boil, add in the rice flour and stir with a wooden spoon.Once the water and flour are well mixed, just let the dough hang out in the pot until it cools enough to handle with your hands.Transfer the dough to a large bowl.Knead with your hands for about a minute. The dough with start to get gummier and hold together better. Cover the bowl with a tea towel or plate so that it doesn’t dry out.Heat a tava or a cast iron pan (any kind of pan will work if you don’t have a tava or a cast iron pan) over medium low heat. Let it heat while you roll out your first rotli.Break off a golf ball sized piece of dough, knead it in your hands a few times and form a disk.Roll the disk into the rice flour and roll out to about 1/32″ thick.Carefully transfer the rolled out rotli to the pan.Let cook until you see bubbles start to form. About a minute or two. Then either using your fingers or a pair of flat tipped tongs flip the rotli.Let cook on the second side until you see more bubbles form. Another minute or two.Turn on a second gas burner on high and transfer the rotli directly to the flame. Let cook for about 15 seconds on each side. (You can also just turn up the flame on the existing burner, move the pan and transfer the rotli to the flame. Just don’t forget to turn the heat back down to medium low!)Repeat the process.
