Prepare the Onion Paste: In a blender, combine the soaked poppy seeds, cumin seeds, black cardamom, black peppercorns, and fried onion. Add some water or yoghurt if needed. Blend until smooth to make the onion paste.
Marinate the Chicken: In a large bowl, mix the ginger and garlic paste, yoghurt, onion paste, orange food colour, citric acid, coriander powder, red chilli powder, mace and nutmeg powder, garam masala, lemon juice, meat tenderizer, and salt. Add the chicken pieces and coat them well. Let it marinate for at least 4-6 hours, or overnight for the best results.
Heat the Oil: In a frying pan, heat 3 tbsp of oil over high flame.
Cook the Chicken: Add the marinated chicken pieces to the pan and cook on high flame for a few minutes until they start to brown. Turn the chicken pieces to cook all sides.
Add Remaining Marinade: Pour the remaining marinade over the chicken, cover the pan with a lid, and cook on low flame until the chicken is tender and fully cooked.
Char the Chicken: Hold each chicken piece with tongs and briefly expose it to direct flame to give it a smoky, charred flavour.
Coal Smoke: To add a traditional smoky flavour, place a small piece of hot charcoal in a bowl and place the bowl in the center of the pan with the cooked chicken. Drizzle a few drops of oil over the charcoal and cover the pan with a lid. Let it smoke for a few minutes, then remove the charcoal.
Serve: Serve the Bihari Chicken Tikka hot with mint chutney, onion rings, and lemon wedges.
