Imli Panna is a quintessential Indian drink which is sweet, salty and sour. Imagine that explosion of tastes and flavours. I put soda in mine but plain old water works pretty well and is traditional. The cumin seeds and mint may be optional but I highly recommend using them to make the drink burst with flavours that is all of the street styled drink that makes it happen.
