1/2 melon or cataloupe
1 tbsp lemon juice, freshly squeezed
4 tbsp sugar
1/2 cup water
Peel the melon and remove the seeds. Coarsely dice the flesh, then transfer it to the jar of a blender. Pour in the lemon juice, sugar and water, then pulse until smooth.
Pour the mixture into a large glass or metal pan, large enough so that the liquid will be less than 1 cm thick. Freeze until the mixture becomes a firm slush, about 40 minutes.
Scrape the surface with a fork and spoon out the shavings into transparent glasses to serve.
