Put the chopped melon in the freezer for a couple of hours This helps the ice cream machine along
Blend the melon with the sugar until very smooth and frothy
Add the cream and blend further
Pour the melon mixture into the ice cream machine until it has the consistency of soft ice cream With the machine still going add in the whisked whites These will become incorporated into the ice cream making it softer
I have made this ice cream without the egg white sucsessfully
