Put rawa in a big bowl and add a pinch of salt. Sprinkle little hot water and mix well. Put a clean thin cloth on a idli plate and spread the rawa and steam it for 15 to 20 minutes.
Meantime, fry the cashew nuts in a teaspoon of ghee. When rawa is steamed well, remove it and put it in a bowl. Add sugar, coconut gratings, cardamom power, fried cashew nuts and ghee. Mix thoroughly.
Note: You have to add everything in the steamed rawa when it is warm. Then only the ghee and sugar will blend well with the rawa.
