Notes
Poori Masala aka Potato|Aloo Masala is the best combo with Poori however can be had with Chapatti or Dosa As well.
The same masala can be prepared thick and used as a stuffing for Masala Dosa.
Usually we add Pottukadalai (Roasted Gram Dal) powder to the masala after adding water it not only makes the mixture thick but also gives a nice flavor.
