A pungent, tangy North Indian specialty infused with robust pickling spices, mustard seeds, fenugreek, nigella seeds, and fresh green chillies.
Whisk yogurt with achari masala, kalonji, ginger-garlic paste, Kashmiri chili powder, and salt; fold in the paneer gently and rest 45 minutes.
Thread paneer cubes onto skewers, alternating with onion petals.
Cook over high heat or under a hot grill, basting with mustard oil.
Grill until light char spots appear; paneer cooks quickly so do not overcook.
Serve hot with lemon wedges and mint chutney.
