Heat ghee in a non-sticky pan. Add mashed sweet potatoes and sauté for 12-15 mins.
Add grated coconut, green cardamom powder, almonds & cashews, raisins and sugar. Mix well.
Keep stirring until the mixture comes together as a single mass.
When the mixture is still warm, shape them into small balls.
Put grated coconut in a plate and roll the balls over it.
Place them in the fridge for 10-15 mins and serve.
