Whisk all the ingredients (except oil) well to remove any lumps.The resulting batter will be of the consistency of pancake batter.
Over medium-high heat, add a teaspoon of oil to a shallow frying pan.
Pour a ladle of the batter on the pan and let it spread on its own.
The pancake will now start to rise and bubbles will form. Wait till the bubbles start to burst (around 1 - 2 minutes) and that's the cue to flip it over and cook the other side (1 - 2 minutes more) (Note: It will only bubble over if you use baking soda and powder - if not using cook it like a regular roti and when you see the color change indicating it is cooked, flip it over)
