First prepare jaggery syrup.Mix jaggery with water and heat it up for few mins until it is slightly thick(no consistency needs to be checked).Heat it up until jaggery gets dissolved.Strain the jaggery syrup to remove impurities.
Strain the syrup and then, collect it in a bowl.Heat it up and cook for few mins to make the syrup thick like honey in consistency.
Measure and take raw rice along with other dals. Soak together in water for 2 to 3 hours, Set aside.
Rinse it well, then add it to a mixer jar.Add water as little as possible and grind into a slightly coarse thickish batter.
It should be this thick. Transfer to a mixing bowl, add jaggery syrup.
Mix well to form a flowing batter slightly thicker than dosa batter.Add coconut and cardamom powder.
Finally heat a dosa tawa. Take a laddle full of batter and pour it on the tawa ,spread it slightly. Drizzle oil.Cook in low medium flame.
Flip to other side for cooking and cook till golden brown and the ends start turning crisp. Similarly repeat to finish the batter.Serve hot with butter!
