Add 3 cups of whole milk to a heavy bottom pot on a medium flame.
To this add 4 Tbsp's of Thandai Masala. Mix well. Make sure there are no lumps.
Once the milk starts to simmer add sugar. Mix well.
Now let milk simmer for about 10 mins. Stir in between to make sure, milk doesn't stick to the bottom of the pan.
Strain it and let it cool. Once completely cool, store in an airtight glass bottle in the refrigerator.
The milk stays fresh upto 3-4 days. Enjoy Cold.
