Percyn, everone drools over your photographs of food. In Bombay we call the chaat in the second photograph Dahi Batata Puri, puris stuffed with boiled batata ie potato with red chilli powder and salt, generous scoops of whipped dahi ie yogurt poured on them, scattered with salt-red chilli powder- roasted jeera powder, and boiled mung beansprouts scattered over them with chopped coriander leaves, then offered with sweet-n-sour date-tamarind chutney and hot green chilli-coriander leaf chutney on the side. Then we have the Sev Dahi Batata Puri, which is the same thing with fried fine gramflour vermicelli ie sev sprinkled on top, giving a different texture and taste. Then we have the Dahi Pakodi Puri, using small dal fritters or vadas previously softened in hot water for stuffing the puris instead of potato, everything else being the same. Then we have the Sev Batata Puri, which is like Sev Dahi Batata Puri without the dahi or yogurt, and made with the crisp flat puris used in Bhel- not the puffed puris. Here we have finely chopped onion and/or tomato and/or green chillies also scattered on top if you wish, and finely chopped raw green mango in season. The wonderful Pani Puri is assembled with puffed puris, boiled mung beansprouts(a Bombay thing) and/or boiled channa, date-tamarind chutney, and a chilli-hot green spicy liquid which is the pani. Make a hole in the puri, stuff with sprouts, dip in pani and put in your eager mouth. Some panipuri wallas use soft boondis for stuffing, some people prefer yellow peas ragra or ghugni for stuffing. In Calcutta they like spiced boiled potato in their Phoochkas as they call them. In Delhi they have potato and/or boondis in their Gol Guppas. My friends and I always start with the Pani Puris, then on to the Dahi Batata Puris, back to more Pani Puris. Sometimes we have Sev Batata Puris and Bhel instead of Dahi Batata Puris. And it always ends with gorgeous Kulfis! Malai, kesar(saffron), pistachio, rose, coconut, or a mixture of these melting creamy chilled confections with falooda. Mmmmm! This is Bombay.
