Heat oil and fry Cumin seeds, Green Chillies, Curry Leaves, Red Chillies, and Ginger.
Add chopped Onion and fry till the raw smell is gone. Add Ridged Gourd pieces, add Mirchi Powder, Turmeric, and Salt, mix well. Cover it and cook on medium flame until oil separates.
When the oil separates, break the Egg on the Curry, and without stirring, cover it and let it cook on a medium flame for 3-4 minutes.
After three minutes, cut it into pieces with a ladle, mix it well and fry till the oil separates from the Curry. It takes about 12-15 minutes for the Curry to cook and oil to separate.
When the oil comes to the surface, add the chopped Green Coriander and Garam Masala and remove them from the fire.
It tastes excellent with Rice, Rotis as well as Puris.
