Marinated in spiced yoghurt, Kashmiri chillies, and garlic, then roasted over roaring tandoor charcoal embers with charred edges.
Pressure-cook the mince with the chana dal, half the onion, ginger-garlic paste, dried red chilies, garam masala, and salt until completely tender and dry.
Pound or grind the mixture without water into a smooth, sticky paste; chill well.
Fry the remaining onion until crisp; form balls of the mince paste, fill each with a little crispy onion, and flatten into patties.
Dip each patty in the beaten egg.
Shallow-fry in ghee over medium heat until dark golden brown and crisp on both sides.
Serve hot with onion rings, lemon wedges, and green chutney.
