In a wide heavy bottomed pan add milk and let it boil
Once it starts boiling increase the flame to high and keep stirring (If you are using stainless /iron pan place a spoon or small cup to reduce the milk from over flowing. Since I used non stick I kept stirring
Stir the milk evenly and make sure it is burnt and keep doing it everytime the milk starts boiling
At one stage milk reduce to 1/3 quantity and become like a cream
Add the jaggery and sugar around that time and keep stirring
Simmer a bit and cook till the sugar melts well and therattipal becomes a mass and drops from the spoon freely. Switch off
