Marinated in spiced yoghurt, Kashmiri chillies, and garlic, then roasted over roaring tandoor charcoal embers with charred edges.
Blanch the spinach and blend with the coriander, mint, green chilies, and ginger-garlic paste into a smooth paste.
Mix the chicken with the yogurt, salt, and half the green masala; rest for 30 minutes.
Heat the ghee and sear the chicken until sealed on all sides.
Add the remaining masala, cover, and cook for 15 minutes until the chicken is done and the gravy thickens.
Serve hot with naan or rice.
