Step 1: Brine. Place the chicken in a large bowl add water salt and some vinegar. What this step does is plump the chicken, makes it juicier. Time: Minimum 1 hour. I kept it for almost 3 hours.

Step 2: Clean and Gash. Drain the brine chicken and wash it with clean water. Pat dry and put gashes on the chicken. This will help the masla to go deep.

Step 3: Marinate. Marinate the chicken with the marinate ingredients above and mix well. Light up the charcoal piece and place it in a dish made out of foil and add ghee to it, immediately covering it. This process is to infuse tandoori flavor.

Step 4: Kadhai Masala Mix: Roast the dry whole kadhai spice mix on a low flame. The idea is to roast the spice mix till the aroma of the roasted spices fill up your senses. They should be light brown in colour. Once the mix cools down, ground it coarsely as shown. I used a grinder, you can use the mortar and pestel.

Step 6: Cook onions. This step is the step where you would need lot of patience. It took me 20 minutes to cook onions very well.

Step 7: Add 1 tsp Ginger garlic paste to the onions. Cook now for 4 -5 minutes. Add turmeric powder now. And 3 slit green chillis.

Step 8: Now add tomatoes (200 gms). I used half a tomato can into the pan. Now add salt to taste to the pan and cook really well. The colour should be really intense and dark. It took me 20 minutes of cooking the tomatoes till the oil seperated.

Step 8.5: Pre heat the oven at Max. While tomatoes are cooking and are half way through add your marinated chicken to the oven grill. I grilled at Max for 10 minutes.

Step 9: Add dry spice and half of kadai chicken spice mix to the tomatoes. Cook for 7-8 minutes and add grilled chicken to it and on high flame mix the chicken and the gravy in the pan. Add the Jus on the grill tray to the pan as well. Cook for 5 - 7 minutes on medium flame and now add cubed onions and capsicum with the remaining kadhai mix masala.

Step 10: Cook the chicken for another 15 minutes with cover on pot. You can add water to make it with gravy. I did not because I like my Kadhai chicken with thick gravy. In the end add kastoori methi and 1 tbsp cooking cream. Stop cooking and mix well.
