The successful inventor of ice cream soda, the brilliant Robert Green promised his fans that he would create a grape flavored ice cream in time for the 1876 World Fair. However, Green was unaware that grapes contain the molecule Anthocyanin, which prevents freezing. He failed miserably.
apple, banana, grape, papaya, watermelon, cantaloupe, kiwi, blueberry, etc... i've never seen them as ice cream.
