Heat oil in a large deep saucepan and once hot, add 1 teaspoon mustard seeds.
Then, add 1/2 teaspoon urad dal and sauté for a few seconds until light brown.
Stir in 8-10 curry leaves and 2 chopped or slit green chilies/Serrano/jalapenos.
Once all the water is almost absorbed, remove the lid, add 1/4 cup to 1/2 cup grated coconut (fresh is best but you can use frozen too; just thaw before using) and give it a gentle mix.
