Chop watermelon in to cubes and remove the seeds. Put them in a blender along with sugar, salt and pepper. Blend everything well in to fine puree.
Add some water and adjust sugar as per the desired sweetness. Pour in to glasses and serve the juice topped with ice cubes. Watermelon juice helps to beat the heat from SUN.
Notes
You can include some mint leaves while blending to enhance the flavor.
A pinch of chaat masala also gives nice twist to the juice.
