Heat ghee in a non-stick pan.
Add the vermicelli and roast on low flame for around 10 minutes till light brown.
Add the condensed milk and mix well to incorporate. You will see the vermicelli and milk collecting itself into a mass.
Switch off the flame and spread the mixture on a well greased plate.
Cut into shapes, garnish with nuts and serve. I made it into flat balls, handling the mixture when it was slightly hot.
