What pie made from a Florida citrus fruit is a signature Southern dessert? Key lime pie. It is a Floridian dessert traditionally made with Key lime juice, egg yolks, sweetened condensed milk, and a graham cracker crust.

The pie is associated especially with Key West and the Florida Keys. Its filling thickens because acidic lime juice reacts with proteins in the egg yolks and condensed milk; most recipes are baked briefly to pasteurize the eggs and set the custard. It may be topped with whipped cream or meringue.

Key limes are smaller, seedier, more aromatic, and more acidic than the common Persian limes found in most American supermarkets. They also turn yellow when fully ripe, so authentic filling is naturally pale yellow rather than bright green.

The dessert’s exact origin is debated. Recipes resembling it appeared in the 1930s, while the popular story crediting a Key West cook named Aunt Sally has no firm historical evidence. Florida officially named it the state pie in 2006.
