Cherry pie is a pie baked with a cherry filling. Traditionally, cherry pie is made with tart rather than sweet cherries as it is easier to control how sweet the pie eventually becomes and also eventually translates to a sharper taste. Morello cherries are one of the most common kinds of cherry used, but other varieties such as the black cherry may also be used.
Cherry pie is associated with North America, Donauwelle in Germany and Austria. It is a very popular treat in North America and prior to the advent of refrigeration it was most commonly eaten in midsummer (harvest of cherries in North America coincides with Canada Day on July 1 and America's Independence Day on July 4.)
Cherry pie is often eaten with whipped cream or ice cream. A common preparation tradition in the United States is to decorate the crust with ornate pastry patterns.
Cherry pie as a dish enjoys a strong history in the United States and is often regarded as a "great American dish". A cherry pie figures prominently in Billy Boy, a nursery rhyme. The song by Warrant named "Cherry Pie", from their album of the same name is one of the group's most popular songs. In a more negative vein, H. Rap Brown famously claimed that "violence is as American as cherry pie".
