Take a wok or a frying pan and heat it on a low flame on your gas stove.
When the frying pan is hot enough, put 1 tbsp of coriander seeds first to dry and roast them.
Stir it till you smell the aroma. Take care that you do not roast them too much so that the seeds change their color.
Now, add 1 tbsp of cumin seeds and 1 tbsp of fennel seeds to it and dry roast all three spices on a low to medium flame. Stir them continuously so that they do not get burnt. Transfer them to a separate plate when they are roasted and you notice a little bit of smoke coming from the spices.
Now, add 50 gms of dry red chilies to the pan. Stir them continuously to roast them slightly. It should not get burnt or change color. Transfer them onto a plate.
Then put 50 gms of chickpeas into the pan, stir them continuously to get rid of the moisture, and transfer them onto the plate.
Now put 1 tbsp of dry pomegranate seeds (anar dana) in the pan and stir them.
When the pomegranate seeds have lost moisture, add all the other spices such as 2 sticks of cinnamon of 1-inch each, 1 tbsp of Kabab chini (tailed pepper, allspice, or cubeb), 1 tbsp of black pepper, 2 tbsp of poppy seeds (khus khus), 4 pieces of mace, 20 pieces of cloves, 6 pieces of black cardamom, 1 piece of star anise, 2 sticks of Piper Longum or long pepper (Pippali) of 1-inch each, and 15 pieces of green cardamom. Stir the ingredients for about half a minute.
Add the roasted coriander seeds, cumin seeds, and fennel seeds to it. Do not forget to stir the spices continuously.
Now add 1 tbsp of dry fenugreek leaves (kasturi methi) to it.
Give it a quick stir to roast and mix the dry fenugreek seeds well. Then add 6 medium-sized pieces of bay leaves. You may tear the bay leaves if they are large. Continue stirring.
When you can smell the aroma of the roasted spices, add the nutmeg. You can break it into small pieces.
Give it a final stir and transfer the roasted spices onto a plate. Set it aside so that the spices cool off completely.
Now, take a dry and clean grinder.
Transfer the roasted ingredients into the grinder. You may transfer them in small batches if your grinder is small in size and cannot accommodate all of the ingredients in one go.
Grind the spices into a powder. It is alright if it is coarse.
Now add the next lot to the grinder. If it is the last batch, do not forget to add 1 tbsp turmeric powder to it.
Now, grind it into a fine powder. Check the consistency and grind a couple of times in short intervals for a smooth powder.
Transfer the powder from the grinder onto a plate. Your aromatic kabab masala powder is finally ready to use.
