'''Key lime pie''' is a Floridian dessert pie made with Key lime juice, egg yolks, and sweetened condensed milk. It may be served with no topping, with a meringue topping made from egg whites,<ref name="Conch Cooking, L.P. Artman, Jr., August 1975 Florida Keys Printing & Publishing, page 74">{{cite book |title = Conch Cooking |first = L.P. Jr. |last = Artman |date = August 1975 |publisher = Florida Keys Printing & Publishing |page = 74 }}</ref> or with whipped cream. Traditionally, Key lime pie is made using a graham cracker crust. It may be made with or without baking in a pie crust or without crust.<ref name="sloan">{{cite book |first = David L. |last = Sloan |title = The Key West Lime Pie Cookbook |year = 2013 |publisher = Self-published |isbn = 978-1499621860 |page = 14 }}</ref> The dish is named after the small Key limes, which are more aromatic than the common Persian limes, and which have yellow juice. The filling in a Key lime pie is yellow because ripe key limes are yellow.<ref name="Conch Cooking, L.P. Artman, Jr., August 1975 Florida Keys Printing & Publishing, page 74"/>
The filling is made similarly to a Magic Lemon cream pie, by mixing the ingredients without cooking: the proteins of the egg yolks and condensed milk and the acidic lime juice curdle, thickening the mixture without baking. The pies are usually baked to pasteurize the eggs and thicken the filling further.
==History== Key lime pie is probably derived from the "Magic Lemon Cream Pie" published in a promotional brochure by Borden, a producer of condensed milk, in 1931.<ref name="parks">{{cite book |first = Stella |last = Parks |title = BraveTart: Iconic American Desserts |year = 2017 |isbn = 978-0393634273 |pages = 171–173 |publisher = W.

==Key limes== {{main|Key lime}} thumb|Key limes Key lime (''Citrus aurantifolia'' 'Swingle') is naturalized throughout the Florida Keys. While the tree's thorns make harvesting them less tractable, and the fruit's thin, yellow rind is more perishable than the common Persian limes seen year-round at grocery stores in the United States, Key limes are both more tart and more aromatic. They have not been grown commercially in the U.S. since the 1926 Miami hurricane, and are generally imported from Central or South America.<ref name="parks"/><ref name="nj">{{cite web |title = Our Story |publisher = Nellie & Joe's Famous Key West Lime Juice |url = https://keylimejuice.com/story/# |quote = Key Limes for commercial use have not been grown in the Keys for many years }}</ref> Key lime juice, unlike regular lime juice, is a pale yellow. Bottled Key lime juice, invariably from concentrate, is widely available at retail in the United States.<ref name="nj"/>
