National Frozen Custard Day is observed in the United States every August 8. This day celebrates frozen custard, a dessert invented in 1919 by ice cream vendors Elton and Archie Kohr from Coney Island, New York. Unlike ice cream, frozen custard contains egg yolks in addition to cream and sugar, which gives it a smoother texture and helps it stay cold longer. The dessert gained popularity after being featured at the 1933 World's Fair in Chicago. Frozen custard is particularly favored in Wisconsin, where Milwaukee is often called the unofficial frozen custard capital of the world. To celebrate, people are encouraged to enjoy this delightful treat, typically available in three flavors: vanilla, chocolate, and a daily special, often prepared fresh at dedicated stands.
