Its not like fermenting normal idli dosa batter ,it will have its own characteristic!!but can be enjoyed with any spicy chutney.
Can add more chillies according to your own spice level.
Even green chillies can be added instead of red chillies.
Bring the batter to the consistency that you can pour as a dosa.
I prefer to clean it with help of scissors holding the thorn-less stem area with one hand.
