I must have posted Hillary white pix before and they are easy enough to google.They are really just a strain of pinks mammoth with a more regular shape and are smaller and I guess they don't have the grit near the skin that mammoths can have. The mammoth strains are bigger, less seedy and perhaps have a richer taste than other atemoyas. They are also probably the oldest we know about and were brought to Australia based on one persons' memories of giant "custard apples" someone ate in around 1870 in what was British Guiana at the time. A natural hybrid and I digress.
