Cut open the Sapito melon and make it into balls.
Place the Sapito balls in a bowl with the lemon juice and a pinch of salt. Put to one side.
In a saucepan mix the sugar and water. Bring to a boil and let it boil for 2 minutes, until a syrup is formed. Remove from heat and let it cool completely.
Mix the melon with the syrup and beat to a smooth texture.
Pour the puree into ice pop moulds. Freeze for 4 hours.
Remove from mould and serve chilled.
