What is Key Lime Pie?

Key lime pie is a dessert pie with a greenish-yellow filling made from Key lime juice, condensed milk, or evaporated milk and egg yolks.

The crust is usually made of crumbs from graham crackers, cookies, or digestive biscuits that have been mixed with melted butter.

Lime zest can be added to the mixture for extra flavor.

Unlike other types of pies, it is not sweetened with white sugar.

Key lime pie is a dessert originating from the “Magic Lemon Cream Pie” created in 1931 by Borden Dairy Company as a marketing ploy to sell more of its condensed milk.

The pie was originally called “lemon cream” but changed in 1936 because consumers were confused by the name and thought it contained real lemon juice, which would make it too acidic.

The name was shortened to simply ‘key lime pie’.

Key Lime Pie is available commercially at some supermarkets or from specialty stores such as Trader Joe’s.

Key Lime Pie’s creamy texture and fragrant citrus flavor make it a popular dessert, but if not properly stored, the flavors can quickly degrade and change to an unpleasant sour taste.

Long-term storage in the refrigerator is recommended for up to one week after baking, while freezing may extend that time frame by 2 – 3 months (depending on preference).

As long as you keep the pie tightly wrapped and in a cold, dark place, it will stay fresh for the desired amount of time.
