National Cherry Tart Day is observed worldwide on June 18 each year. This celebration encourages people to bake cherry tarts using fresh cherries, which have a short growing season. While frozen and preserved cherries can be used, they do not provide the same flavor as fresh ones. The day has its roots in the National Cherry Festival held in Michigan, which highlighted the limited culinary use of cherries, with cherry tarts being a common dish featuring a crust and sweet filling. A tart is similar to a pie, flan, or quiche, with the distinction that it typically lacks a top crust. Enjoying a slice of homemade cherry tart, often paired with ice cream or custard, is a popular way to celebrate this holiday.
