About National Key Lime Pie Day
History & origins
National Key Lime Pie Day is commonly listed on September 26. It is an informal U.S. food observance, and the exact founder is unclear. Key lime pie is strongly associated with the Florida Keys. Traditional recipes use juice from Citrus × aurantiifolia (key limes), egg yolks, and sweetened condensed milk in a crust, often graham cracker, sometimes topped with meringue or whipped cream.
Key limes are smaller and more aromatic than typical Persian limes in U.S. grocery stores. Bottled key lime juice is widely used when fresh key limes are scarce. The pie became a regional emblem and then a national dessert menu staple.
Why it matters
Dessert search demand is strong, and the pie has a clear regional story that writes well without fake history.
How to celebrate
Bake or buy a key lime pie. Taste fresh vs bottled juice if you bake. Serve chilled. Share a slice with coffee. Skip green food coloring — pale yellow is traditional.
