Wash and soak the rice, dals together overnight (5 hours minimum).
In a big mixie jar, take the soaked dal & rice mixture, ginger, green chilies, jeera, salt, and palak.
Grind it a smooth batter by adding little water to get a dosa batter consistency.
Mix well. Adjust the consistency of batter adding ¼ cup of water if it is very thick.
Heat dosa pan and pour a ladle full of batter. Spread it & make it thin as per your wish. I always make it thin as my family likes it that way.
After making dosa, keep the flame medium-high and sprinkle chopped onions and drizzle a teaspoon of oil over the dosa.
Cook for 1-2 minutes till dosas turn golden brown and crispy.
Remove the dosa and Enjoy with coconut chutney !
