In a kadai, splutter mustard seeds. Once they crack, add urad dhal and curry leaves.
After the urad dhal turns brown, turn off the stove and pour this into coconut green chilli mixture.
A minute before serving, add the curd.
If you add this before, it will become sour.
The gravy should neither be too watery nor too thick.
You can just mix this with rice and have it with papad or some dry sabzi. Or you can also serve it as a side dish for molagootal.
