Kachori-style fried pastries turn up in North Indian writing as far back as the 17th century, but the onion-stuffed 'pyaaz' version so closely tied to Jodhpur today is a distinctly regional, much later refinement — one that took over the city's breakfast stalls rather than staying a general bazaar snack.
A maida dough is stuffed with a spiced onion filling (often blended with a touch of mashed potato), sealed, and deep-fried until deeply golden and flaky, then served split open with a ladle of potato curry and a spoon of tamarind and green chili chutney. Jodhpur's roadside stalls fry them fresh through the morning for breakfast crowds.
