There is no such thing as grape ice cream. The reason? It has a lot to do with dogs, girls, the 1876 World’s Fair, pharmaceutical companies, and it’s more complicated than you might ever imagine.
After his successful invention of the ice cream soda in 1874, Philadelphia’s Robert Green began to tackle a request from his customers. Green boldly stated, in an 1876 interview with the Pennsylvania Inquirer, “The people are tired of vanilla and chocolate. They want something more.” What Green did not know, is that grapes contain a special molecule Anthocyanin that prevents freezing, so he kept turning up with grape milk.
