First we need to marinate the chicken. Combine the chicken, freshly ground ginger-garlic paste, salt, red chili powder, and lemon juice in a mixing bowl.
Mix well and cover the bowl with a cling wrap and keep aside for at least 20-30minutes, longer the marination more taste and flavour get infused in the meat.
In the meanwhile, let's prepare the chicken curry gravy. Heat the mustard oil in heavy bottom pan.Turn the heat off once the mustard oil begins to smoke.
Let the oil cool down around the normal cooking temperature, add in the whole spices; cinnamon stick, green cardamoms, black cardamoms, dried red chilies, black peppercorns, cloves, and bay leaves. Saute for a few seconds.
Next add in the onions chopped and purée, saute until it turns golden, followed by this add in freshly ground ginger-garlic paste,cook until the raw smell disappears.
Now pour in the tomato purée and continue to cook it, until the oil begins to ooze out from the content.
When the oil separates, add the powdered spices; turmeric, red chili, roasted cumin, and coriander. Give it mix.
Add in the marinated chicken and mix well. Saute for 3-5 minutes so that the chicken turns white in color.
Add 2 -3 cups of water or as much as you need depending on how like the consistency of chicken curry gravy.
Cover and let the chicken simmer in for the next 15-20 minutes or until it's done. Keep checking and stirring 5-7 minutes or as needed.
After 15-20minutes, when the chicken is nearly cooked, remove the lid and cook open for another 5minutes.
When the chicken gets cooked through, add the kasoori methi, coriander leaves, and garam masala. Give it a stir and turn the heat off.
This is an optional step for smoking flavour;In a tempering pan or a small clay pan, place a small bowl containing the red hot wood coal ember.Pour some oil over it and cover with a lid. Let it be like that for 4-5 minutes.Remove the bowl from the clay pan or tempering pan and discard the coal ember. Garnish with fresh sliced ginger and coriander leaves.
