For fantastic khichiya papad chaat, head to the Khau Galli in Bhuleshwar!
The papads are roasted over a coal sigdi, and then coated with two kinds of chutney, red and green. Then it is topped with potatoes, tomatoes, onions, and of course, finally garnished liberally with sev and coriander.
It's seriously tasty, folks. As you can see from the first photo, the papads are nice and thick, so they make a great base. Unlike the usual urad dal papads, khichiya papdi is made of rice and the taste is very different. If you live in Mumbai but haven't yet tried this, you're missing something!
I've only ever seen this in Bhuleshwar, but if you live in a Gujju neighbourhood, let me know if you've spotted this. I'm told Borivali West is another good place to find masala khichiya papad?
