In a nonstick or heavy-bottomed pan, dry roast dry red chilis. Roast them on medium-low heat for a couple of minutes or until they start to get darker in color.
Remove the chilis from the pan and place them into a plate or bowl.
In the same pan, add the rest of the spices and roast them on low-medium heat.
Roast them for 3-4 minutes or until they are aromatic.
Remove these spices from the pan and place them with red chilis.
Let the spices cool down completely. Now add them into a grinder jar and grind them into a coarse powder.
Do not grind the spices into a fine powder. Alternatively, you can also crush the spices into a mortar and pestle.
Storing The Masala
Store this spice blend into an air-tight container or jar and keep it in a cool and dry place.
To retain the freshness of the masala, refrigerate it for up to a month.
You can also freeze this masala for up to six months. For the freezing, store the masala in a freezer-safe container or bag and use it as you need.
Notes
I have used Kashmiri red chilis, so the masala does not become too spicy but provides bright color to the dish. But if you want your Kadai Masala to be spicy, use hot varieties of dry red chilis. Also, you can use half Kashmiri dry red chilis and half the hot chilis.
The texture of the masala should be coarse, so do not grind it into a fine powder.
Use fresh and high-quality whole spices for the best result.
Store the masala in an air-tight container or jar and to retain the freshness, store it in the fridge or freezer.
