Add the flour and salt into a large bowl. Mix well.
Now add oil and mix it well. Break the lumps by rubbing the flour between your palms. Now add warm water little by little and knead a soft, yet stretchy dough.
Cover and let the dough rest for 10-minutes.
Preheat your air fryer or CrispLid at 350F for 7-minutes.
Clean the air-fryer or CrispLid basket and line it with parchment paper.
Meanwhile, divide the dough into small balls and roll them into disc-shaped thin tortillas or rotis. Use a round cookie cutter to cut small discs out of it.
Place the discs on the air-fryer basket.
Cook them for 3-minutes and flip and cook for another 2-minutes.
The tiny puris will puff up and look brown around the edges.
Transfer the puris to a cooling rack.
Use the puris in your favorite chaat recipe and store the rest in an air-tight container.
