Take a frying pan and heat it on a low flame on your gas stove. When it is hot, add 1 tbsp of black pepper, 1 tbsp of cloves, 2 tbsp of coriander seeds, 2 tbsp of cumin seeds, 1 tbsp of fennel seeds, 2 pieces of bay leaves of medium size, 1 piece of black cardamom, 2 one-inch sticks of cinnamon, ½ tbsp of fenugreek seeds, 1 tsp of carrom seeds, and 8 pieces of dry red chilies with their stalks into it.
Stir the ingredients continuously for about 10 minutes to dry roast them. Turn off the flame of your gas stove when the color of the ingredients changes slightly.
Put the pan aside so that the spices cool off completely. While it cools, remove the stalks from the roasted dry red chilies and de-seed the black cardamom pod.
Now, take a clean and dry grinder.
Transfer the roasted spices to the grinder.
Now add 1 tbsp of black salt to the ingredients.
Finally, add 1 tsp of mustard oil. This will act as a preservative and enhance the flavor of the masala powder.
Grind the spices into a fine powder. You may have to grind it a couple of times to get the desired fineness.
Transfer the powder from the grinder to a bowl. Your jhaal muri masala powder is ready to use.
