Prepare marination - Mix all the ingredients listed under marination - turmeric powder, Kashmiri chilli powder ( or chilli powder or paprika or cayenne pepper), lemon juice, salt, curd, vegetable oil, fenugreek leaves, cilantro leaves, coriander powder, cumin powder, pepper powder, garlic paste, ginger paste, garam masala powder and dried mango powder. Refer notes on the type of curd you can use. Kashmiri chilli powder may not be common in American homes. Paprika or cayenne pepper or regular chilli powder are good alternatives. I didn't use fenugreek leaves and dried mango powder.

Make sure that marinade has thick consistency. Adjust salt if needed. Score the chicken so that marinade penetrates faster. Marinate the chicken and refrigerate it overnight.

Preheat oven at 460F. Line a tray with foil and place a rack on the tray. Remove chicken from the marinade, shaking off excess, and place on the rack. Bake for 15 - 20 minutes on one side. Turn it over. Bake on the other side of the chicken for another 15 - 20 minutes. Chicken would be cooked by this time and would have started turning brownish.

To get the charred look like the real tandoori made in the tandoor, broil the oven at 525F. Place the tray with the chicken on the top rack. Keep it on broil mode until the skin gets a charred look. Once the chicken is brownish, take out the tray and turn over the chicken. Keep it back. It took 1 minute on each side for me to attain the brown-blackish texture. Enjoy :)
