Marinated in spiced yoghurt, Kashmiri chillies, and garlic, then roasted over roaring tandoor charcoal embers with charred edges.
Rub the chicken with lemon juice and salt, then coat in a mix of yogurt, cream, cashew paste, ginger-garlic paste, cardamom, and garam masala; refrigerate 4 hours.
Thread the drumsticks onto skewers or arrange on a grill tray.
Cook over medium-high heat or in a hot oven, basting with butter.
Grill gently until golden and cooked to the bone, about 20 minutes, turning often so the cream marinade does not burn.
Serve warm with green chutney and naan.
