What summer picnic or gathering is complete without a chilled slice of tart, cool Key Lime Pie on a paper plate? 

This wildly popular pie originated in the Florida Keys in the mid-19th century. Fresh milk was scarce on the sun-baked tropical islands, but when Borden's was granted a patent for canned milk, which required no refrigeration, Key Lime Pie was born.

Adapting traditional, classic key lime pie for a gluten-free diet is simple and approachable. A gluten-free graham cracker pie crust makes the adaptation easy. 

Some versions of Key Lime Pie are meringue-topped. This version is easier to prepare and a dollop of whipped cream is a nice balance to the acidity of the filling.

Enjoy this gluten-free twist on Key Lime Pie any time you are craving the brightness of summer. 

Note: This recipe for Gluten-Free Key Lime Pie is adapted from a recipe which appears in "Maurice's Tropical Fruit Cook Book."

Recipe Variation

  • If you can't find key limes, you can substitute Persian lime juice in this recipe, but you will lose some of the authentic tart flavor of key limes.
