Learn to make a small batch of curry leaves powder, known as karuveppilai podi. This oil-free spice mix is incredibly versatile and can be used in various ways.
Heat a pan or kadai and add chana dal. Roast over medium-low heat (around level 4) until it turns deep golden brown, then transfer it to a plate.
In the same kadai, roast urad dal until it reaches a deep golden brown color, then transfer it to a plate.
Keep stirring continuously for even roasting, and avoid leaving the dal unattended. A few slightly over-roasted lentils won't affect the taste. Here are the roasted dal.
In the same kadai, roast tamarind, dry red chilies, and whole pepper for a couple of minutes.
Add rinsed and dried curry leaves along with asafoetida, then roast until the curry leaves turn crisp. Let everything cool.
First, grind the roasted curry leaves with salt in a mixer jar until coarsely powdered.
Add the roasted lentils and grind in short intervals, mixing in between, until you achieve a slightly smooth texture.
Transfer the ground podi to a plate, break any lumps, and let it cool completely before storing it in an airtight container.

Notes
Be mindful when adding salt; more can be added later when mixing with rice.
Adjust the amount of pepper and red chilies according to taste.
Tamarind is optional but enhances the flavor.
Roasting time varies based on the utensil and heat; lentils should be deep golden, and curry leaves should be crisp.
Asafoetida can also be added while roasting the lentils.
