Dry roast the roasted split gram ( pottukadalai) until fragrant and set it aside. Allow it cool down and then transfer it to a blender/ mixer and powder it to a fine powder.
Grind the Sugar and Cardamom to a powdered consistency.
Pass the ground split gram flour, sugar and cardamom through a sieve, to ensure there are no lumps.
Heat 2 Tbsp of ghee and add the cashews. Fry in low flame until golden brown and add it to the bowl with ground roasted gram flour. Mix with spoon.
Heat the remaining ghee in low flame and add 1 large ladle of ghee at a time to the mixture. Do not be tempted to add all together in one go as the ladoo's will not turn out stiff.
Take small portions of the mixture and press gently between your palm. Then roll into a round shape like ladoo. If the mixture is too crumbly, add more ghee.
Repeat the process for ladoo with the remaining mixture.
