Has anyone mentioned Eskimo Pies yet? That is so American that its inventor, actually Danish-born, secured a patent for the ice-cream concoction exactly 80 years ago yesterday (Jan. 24, 1921). From Wikipedia:
Danish immigrant Christian Kent Nelson, a schoolteacher and candy store owner, claimed to have received the inspiration for the Eskimo Pie in 1920 in Onawa, Iowa, when a boy in his store was unable to decide whether to spend his money on ice cream or a chocolate bar. After experimenting with different ways to adhere melted chocolate to bricks of ice cream, Nelson began selling his invention under the name "I-Scream Bars." In 1921, he filed for a patent, and secured an agreement with local chocolate producer Russell C. Stover to mass-produce them under the new trademarked name "Eskimo Pie" (a name suggested by Mrs. Stover), and to create the Eskimo Pie Corporation. After patent 1,404,539 was issued on January 24, 1922, Nelson franchised the product, allowing ice cream manufacturers to produce them under that name. The patent, which applied to any type of frozen material covered with candy, was invalidated in 1929. One of the earliest advertisements for Eskimo Pies appeared in the November 3, 1921 issue of the Iowa City Press-Citizen.
