For the tempering- Heat oil in a pan, add mustard seeds, once they splutter add, urad dal, when it turns golden brown, add curry leaves, red chillies, and asafoetida. When the curry leaves turn crisp, pour the tempering over the prepared coconut paste. Enjoy with idlis/dosas. Since fresh coconut is used here, it is best to consume it within 1-2 days. Store it in the refrigerator.
