Cherry pie

Cherry pie is a pie baked with a cherry filling. Traditionally, cherry pie is made with sour cherries rather than sweet cherries. 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 Europe and North America and is mentioned in the lyrics of American folk songs such as "Billy Boy". Due to the cherry harvest in midsummer coinciding with Canada Day on July 1 and America's Independence Day on July 4, cherry pie is often served on these holidays. It is also associated with the celebration of Washington's Birthday because of the legend of young Washington's honesty regarding the felling of a cherry tree.
