Take two ziploc covers, grease it with few drops of oil. Keep one ball at a time and put the other greased cover over it and use a flat bottomed bowl to press it.
You can do this with your fingers as well. I do this way to get a good shape and also makes job easier.
After flattening with the bowl, it is a must to flatten with your fingers to make it thin and even.
Carefully take off from zip lock cover by inverting it on one hand and drop in hot oil. Cook in medium flame.
