1. Freeze 850g of the diced melon for at least 2 hours.
2. Add the frozen melon pieces and the Alpro Coconut Original into a blender and blend for a few seconds until the mixture is nice and smooth.
3. Spoon into 6 dishes, top with the remaining melon pieces and a sprig of mint. Serve immediately. If not serving rightaway, place in a freezer, and stir every few hours.
