Take a frying pan and heat it on a medium to low flame on your gas oven.
In the frying pan first add 3 tbsp of cumin seeds and 3 tbsp of coriander seeds.
Then, add 30 pieces of dry red chili buttons to it.
Stir the ingredients occasionally to roast them for about 2 to 3 minutes until the spices turn slightly golden in color and you can smell the fragrance.
Turn the flame off and leave it for some time for the spices to cool off.
When it is completely cold, transfer the roasted spices into a mortar & pestle (hamandista).
Crush them until you get a coarse mixture. You may use a grinder for a finer powder if you want.
Now, once again, turn on your gas stove to heat the frying pan and put 1 tsp black pepper in it along with ½ tsp carom seeds to dry roast them.
Do not forget to stir them as well.
Turn the flame off and then add 5 pieces of cloves to it. Stir all the spices for another minute or so.
Set it aside and let it cool completely at room temperature.
Then transfer the spices to your grinder.
Now add 1/3 tsp lemon salt (Tatri) to it.
Also add 1 tsp black salt.
Then add 1 tbsp of amchur or dried mango powder as well.
Finally, add ½ tsp table salt.
Grind the contents nicely to get a fine powder. Transfer it to a small, dry glass bowl.
Add the spices you crushed before to this powder and mix them nicely. Your dahi vada masala powder is ready.
