Heat oil for deep frying on a medium flame.
Make equal-sized dough balls, and keep them covered, so they don't dry.
I use a tortilla press to make the puris. Use two square parchment papers.
Place a dough ball on the base side of the tortilla press with the pressing wand side.
Place another parchment paper on the top of the ball. Bring the other side of the tortilla press to rest on the dough ball, and press with the wand.
Just press once, and you will have perfect puris.
You can also use two flat plates to make the puris or roll them using a rolling pin. Dab the dough ball with oil, or use loose buckwheat flour to roll the puris. Roll them about 5 inches in diameter. They are fairly thicker than the regular puris.
