Roast until the rice starts to puff up and crackle and change color to golden brown.
Remove from flame and set aside to cool.
Once it gets cold grind it into a powder.
Add the grated coconut to the rice powder and coarsely grind it together for few seconds in the mixer-grinder and set aside.
In a pan add grated jaggery and pour water to it as per required and melt it on a low flame.
Strain and pour it to the rice and coconut mixture.
Add cardamom powder and mix well.
Allow the mixture to cool a bit.
Now take small portions of the mixture and shape it into medium sized balls. (apply little ghee in your hands before making balls to prevent the mixture from sticking).
Let it cool down and serve along with tea or coffee.
