Thiruvadirai falls in the month of Marghazhi and is auspicious for Lord Shiva. Thiruvadirai kali and kootu (thaalagam) are traditional dishes prepared on this day. My mom's recipe below.

Tamarind, red chilli powder, asafoetida powder, curry leaves.
To fry: Channa dal, coriander seeds, dried red chillies.
Add salt and turmeric and steam the vegetables in a pressure cooker. Fry the frying ingredients and powder. After spluttering the mustard seeds in oil, add a small quantity of tamarind water, red chilli powder to taste. Add the steamed vegetables to this and stir for sometime. Finally, add powder from previous step and asafoetida powder. Sprinkle curry leaves and mix.
