Overview: Few treats are as popular or American. At the 1904 St. Louis World's Fair, a man selling waffles beside an ice cream vendor put a scoop of ice cream in a rolled-up waffle when his neighbor ran out of dishes--the totable treat caught on and is still a favorite way to enjoy the frozen confection. But whether in a sundae, ice cream sandwich, banana split, parfait, or baked Alaska, ice cream is a dessert we can't desert.
