How to make
Clean the watermelon and melon from their seeds. Cut them into small pieces.
Put them in the jug of a blender and blend them. Make sure to blend them a few times, so that no chunky pieces remain.
Strain the mixture through a sieve and refrigerate it for a few hours. If the melon and watermelon were in the refrigerator, there is no need and in that case directly serve the fruit soup in suitable bowls.
