Immediately after making ghee use the residue for making laddu .Heat the ghee with residue in a heavy-bottomed pan, heat the ghee along with the leftover ghee residue. Let it melt and become aromatic.
Add wheat flour to the pan and roast on low flame, stirring continuously. Keep roasting until the flour turns golden brown and releases a nutty aroma. This may take around 10–12 minutes. Look for a wet sand consistency (not too dry)
Switch off the flame and let the mixture cool slightly. Then add powdered jaggery and mix well. The residual heat will melt the jaggery and bind the mixture.
Optional (Add cardamom and nuts: Stir in cardamom powder and chopped nuts if using. )
Mix thoroughly. Shape into round laddus: While the mixture is at bearable heat, shape it into small, bite-sized balls using your palms.
Notes
If the mixture cools down completely the ladies won't hold together and hold the shape.Add a tsp or two of hot ghee if the mixture is too dry. this will help in shaping the mixture well.
