Add coconut, roasted gram lentils, garlic, chili, cumin seeds, sugar, lemon juice and water to a blender and blend until you get smooth chutney.
Add more water if needed to get to the desired consistency.
Take out the chutney in a serving bowl.
Heat oil in a tadka pan over medium heat.
Add mustard seeds and allow them to pop.
Turn the heat off and then add asafetida/hing and curry leaves.
Be careful as you add curry leaves as the oil may splatter.
Pour the tadka over the chutney and stir in.
