My Paternal Grandmother (Late Mrs Jayalakshmi Sundaresa Iyer) always made this ladoo when she made Ghee. This is made from the "Kasandu" leftover fat of the ghee which stays behind after you filter the ghee.
This measurement is for the leftovers from 4 sticks of butter.After you filter the ghee, scrape the vessel and bring all the Kasandu out, add ¾th cup of Mung Dal flour (I had Mung flour with skin, got it from the indian store), Start by sauteing the flour in the same vessel until the raw smell of the flour goes away.
Roast the flour till it becomes slightly red.
Add ½ cup of powdered sugar, (confectioners sugar)
Transfer the contents to a basin.Add some raisins and or cashew nuts to the vessel and fry and then add them to the basin.
Mix with a spoon and make ladoos when you can handle the heat.
Try and make them while they are still warm so it will catch on more quickly.When my kids were small, my husband used to give these sweets different names so they will become intrigued, so these were called "Power Balls" They still go by that name in our house, It gives an instant burst of energy.
