Wash and soak rice for 3 hours firstly.
Meanwhile, peel the bottle gourd and remove the soft portion in the middle and the seeds.
Chop the firm part of the bottle gourd finely.
In a mixie, grind red chilli, asafoetida and salt first.
Then add rice drained from water and grind smoothly. Add water as you grind as needed.
Transfer to the mixing bowl and add the finely chopped bottle gourd to this and grind smoothly.
Mix both of this ground items well and adjust the water consistency as per your need. I had it like our idli dosa batter. Neither too thick nor thin.
Temper the items given under to temper table and add it to the batter, mix well.
Heat dosa pan and dizzle some oil, spread the batter evenly slightly thick.
Cook covered and flip and cook until done.
