Knead the dough for 30 seconds, make 8 equal balls, and keep them aside. Make 8 equal balls of puran as well.
Take a dough ball, spread it with your fingers, and stuff the puran. Slide the dough upwards and keep pushing the puran slowly inside the dough with your fingers. Completely cover the puran with a dough and pinch the edge to seal.
Meanwhile, preheat a non stick flat griddle on medium heat.
Line a few papers on a countertop for transferring the cooked roti.
Sprinkle some rice flour on a work surface, flatten the stuffed dough gently, and sprinkle some flour on the top. Flatten the dough with your fingers carefully. It should be around 3-4 inches in circumference. This helps the puran reach the edges while rolling the poli.
Roll out a dough into a thin roti with a rolling pin around 7-8 inches in circumference. You can dust some rice flour if required.
Lift the roti slightly and carefully roll it over a rolling pin halfway. Slowly transfer it on a hot griddle. It helps to transfer the roti easily without breaking apart.
Let the roti cook until you see small bubbles on the top. Next, flip it to the other side and let it cook till you see light brown spots.
Flip the roti again and cook for another minute, remove it from the griddle, and transfer it on a paper.
Roll the rest of the rotis and cook them in the same manner. Keep space between the cooked puran poli and let them cool down completely.
Stack up the puran polis one over another or fold them into half in an airtight container.
