Key lime pie traces its roots back to Key West, Florida. Most sources believe the first written recipe for Key Lime Pie is from 1855 by a woman known as “Aunt Sally” – the cook at the home of Key West’s first millionaire William Curry. Curry began importing cans of sweetened condensed milk to Key West, where its resistance to spoilage made it very popular among the fishermen who were a part of the boom of sponge fishing that took place in the Keys’ shallow waters at the time. It is thought that these sponge fishermen were the ones who invented the earliest recipes for Key Lime Pie, combining Key limes, pelican eggs, and the sweetened condensed milk. Key Lime Pie has etched a spot in the culture of Florida, and there is now an annual Key Lime Pie Festival
 in Cape Canaveral, and in 2006, Florida passed legislation naming Key lime pie the official pie of the state of Florida.
