Wash and dry the curry leaves with paper towel. The drier the leaves, the faster the roasting process.
Dry roast them on a heavy bottomed pan for 10-15 minutes, on low heat, moving them around often.
Dry roast other ingredients- peanuts, red chilies, sesame seeds and flax seeds ,dals, tamarind and garlic. The dals should turn fragarant and nutty. The peanuts should be crunchy inside.
The garlic should be slow roasted from all sides.
Let everything cool down.
Add salt, asafetida and sugar(jaggery). These do not need to be roasted.
Add the tamarind, chilies and peanuts to the blender first. Blend finely and then add rest of the ingredients.Blend till they are a powder.
Taste and adjust the salt. The podi's spice level will reduce with time.
