Grate four corn cobs using a coarse grater and finely chop the kernels from the fifth cob. Set aside.
Heat oil or ghee in a heavy-bottomed pan over medium heat.
Add cumin seeds and let them splutter, then add asafoetida and ginger paste.
When the ginger paste turns light brown and aromatic, add the grated and chopped corn.
Add green chili paste and salt, mixing well to combine.
Slowly pour in the milk while stirring constantly to prevent curdling.
Bring the mixture to a boil, then reduce heat and simmer until corn is tender and mixture thickens, about 10-12 minutes.
Stir frequently to prevent sticking to the bottom of the pan.
Garnish with fresh chopped coriander and grated coconut before serving.
