Marinated in spiced yoghurt, Kashmiri chillies, and garlic, then roasted over roaring tandoor charcoal embers with charred edges.
Coarsely crush the mustard, fennel and fenugreek seeds together.
Whisk the yogurt with the crushed seeds, nigella, turmeric, mustard oil and salt; coat the paneer cubes and rest 1 hour.
Thread the paneer onto skewers, leaving small gaps.
Grill over medium-high heat, turning gently, until golden and charred at the tips.
Serve hot with onion rings and mint chutney.
