Key Lime Pie Recipe

Key Lime Pie Recipe an old fashioned pie made with Florida key limes, sweetened condensed milk, meringue and coconut.

The first recipe was recorded in 1930. It originated in Key West, a seaport in Florida and named for the small key limes growing in the Florida Keys.

July 1, 2006, legislation was passed making it the "Official Pie of the State of Florida".

The original pie contained sweetened condensed milk because fresh milk was hard to get and hard to keep fresh due to the lack of refrigeration in those days.

Because this is an uncooked pie that contains eggs, it is important to bake the meringue and not substitute whipped cream for the topping , in order to cook the eggs properly, for safety reasons.
