Puri for Pani Puri is a small cup like round deep fried crisp hollow vessel made with semolina flour and filled with chickpeas, diced potatoes and spiced water with a dash of chaat masala.
1. Do not add oil to the dough while kneading as the puris will become soft later.
2. Formation of gluten strands is important and there has to be elasticity in the dough, which is the key crispy puris even after they are cooled.
3. Avoid adding too much flour/maida to the dough.
4. Always cover the dough and rolled puris with a damp cloth even while rolling rest of the puris. if the dough becomes dry, you will not be able to roll the dough easily. If the puris become dry, then the puris will not puff up.
5. The puris have to be rolled very thin, otherwise the puris won’t puff up well and will remain soft from within.
6. Fry the puris in moderately hot oil. If the oil is not hot enough, the puris will absorb oil and become soaked in oil and they will also become soft. Too hot oil will burn the puris.
7. Most important tip: After all this, if your puris are still slightly soft, heat an oven at 200F and place the puris on a baking tray and let them sit in the oven for 20 to 25 minutes at 200F. This will make them crispy.
