Many vendors stuff the patties with spiced chana dal or peas before frying, so the tikki is crisp outside with a second texture inside.
Mashed, spiced potato patties are shallow-fried on a flat griddle until a deep golden crust forms, then topped with chickpea curry, whisked yogurt, tamarind and mint chutneys, and a scatter of chopped onion and sev. Vendors across Delhi assemble it to order on a disposable plate for eating right at the cart.
