Ok, the colours are not a 100% natural, but doesn't it look sooo cool?
It reminds me of the luxury of a hotel breakfast on the warm side of the globe, drinks by the pool and big fat hot summer....
1/4 watermelon, cut in small cubes
a handful of ice cubes
1tbs freshly squeezed lemon juice
sugar to taste depending on the ripeness of the melon ( I prefer it without sugar; it's more refreshing and just sweet enough)
all the ingredients in a blender and blend until smooth.
