This name is common in West Bengal and Assam in eastern India. Its flavor is distinct from Mumbai’s pani puri since the filling is a combination of mashed potatoes and boiled gram. There is an option between sweet tamarind and spicy water in the chutney, which is more sour than sweet. The puris have grown and become darker. The chaat vendors in Kolkata are pros at adjusting the mashed potato’s flavor to suit your preferences. Jharkhand and Bihar both have certain regions with the same name.
