The chili papads can be dried in the hot sun for 15 minutes on one side and for 15 on the other side if you are planning to deep-fry them immediately. If however, you wish to store them for later, please dry them for 30 minutes on each side. You can use a grass mat, or a clean cotton cloth, or large stainless steel platters, trays, or plates to spread out the papads for drying.
