You will need;
-left over fudge
-100mls of evaporated milk
Simply add the ingredients to a blender or food processor, and blitz until smooth or only slightly lumpy in consistency.
Then pour into an air tight container and freeze over night.
Best enjoyed with chocolate sauce. Delightfully decadent and so cheap to make its unbelievable. Though it is very rich so don't serve too much at once.
