Sieve besan. Roast it a bit and keep aside. Heat ghee and add besan to it and mix well. Cook till the cooked smell comes. Add the cardamoms and powdered cashews and other nuts. Let it cool a bit and then add the powdered sugar and mix well. Transfer into another vessel and let it cool just so much that you can shape it. Grease your palms with a little ghee while shaping into balls.
