Marinated in spiced yoghurt, Kashmiri chillies, and garlic, then roasted over roaring tandoor charcoal embers with charred edges.
Parboil the baby potatoes, then scoop out a small cavity in each.
Mix crumbled paneer with cashews, half the tandoori masala, and a pinch of salt; stuff each potato.
Whisk yogurt with remaining tandoori masala, Kashmiri chili powder, ginger-garlic paste, and salt; coat the potatoes and rest 30 minutes.
Thread the stuffed potatoes onto skewers or place on a grill tray.
Cook over high heat, basting with mustard oil, until blistered and charred in spots.
Serve hot with mint chutney and lemon wedges.
