Dahipuri, or Dahi puri

Dahipuri, or Dahi puri

The round, hard, puffy puri shell is first broken on top and partially filled with the main stuffing of mashed potatoes or chickpeas. A little haldi powder and/or chilli powder may be added for taste, as well as a pinch of salt. Sweet tamarind chutney and spicy green chutney are poured into the shell on top of the stuffing. Finally, sweetened beaten yoghurt is generously poured over the shell, and the finished product is garnished with sprinklings of crushed sev, moong dal and finely chopped coriander leaves.
Dahi puri typically comes 5 or 6 dahi puris per plate. Unlike pani puri, dahi puri is not served one morsel at a time, but all at once. Each dahi puri is intended to be eaten whole, like the pani puri, so that the spectrum of flavors and textures within may hit the mouth together for full effect
