Marinated in spiced yoghurt, Kashmiri chillies, and garlic, then roasted over roaring tandoor charcoal embers with charred edges.
Coat the chicken in the yogurt, cashew paste, ginger-garlic paste, half the green chilies and half the garam masala; rest 1 hour.
Melt the butter in a kadhai and sear the chicken strips with their marinade until nearly cooked.
Add 1/2 cup water and simmer 10 minutes until a silky gravy coats the chicken.
Stir in the cream, remaining garam masala and green chilies, garnish with coriander and serve with naan.
