If you have a mixer grinder that’s great your job is easy now, in case not you will have to do it the hard way like i did.
1)First take a watermelon, cut it into pieces and take its juice out.(people not having a juicer can use a grater and a large strainer)
2)cut the leftover watermelon in small pieces to act as semi solid particles in the cooler.
3)take two jars
4)put the pieces of watermelon at the bottom of the jar
5)add pinch of salt, pepper, chaat masala and sugar to it.
6)add the watermelon juice to the jar and fill them half
7) now put the chilled sprite to fill the jar to the brim
8)add ice cubes if required and stir well
That’s it the watermelon cooler it ready.
