Khari, the puff pastry that melts in your mouth is a staple of Parsi and Irani cafes. Of course it had to be from Iran. Sure enough, when you search for puff pastry from Iran you get lots of recipes and names of sweets like Zabaan and Naan Khamei. They are sweet, unlike this, whose very name means salty. Apart from the sugar, the recipes seem like they could be for this. A khari and a cutting chai is the typical Mumbai pick-me-up, but it may have started life elsewhere.
