Key West Florida, in addition to being famous as the southernmost speck of land in the continental United States, is an Island of wonderful taste traditions. Most notable is the Key Lime Pie, a delicious but surprisingly simple dessert to make. No one knows for certain how and when Key Lime Pie began, except that it was around at the time of the early settlers in the Keys. One speculation is that a locally made home-style custard pie became a favorite when made with the new pre-sweetened condensed milk. This canned milk product had become popular in the southernmost city because of its long shelf life and no need for refrigeration.
