  • 2 cups graham-crackers finely-crushed
  • 1 stick unsalted butter melted
  • 3 tablespoons sugar
  • 1 teaspoon unflavored gelatin
  • 2 tablespoons cold water
  • 2 egg yolks
  • ½ cup Key lime juice freshly squeezed if available
  • 14 ounces sweetened condensed milk
  • Grand Marnier ® Whipped Cream recipe below
  • 1 lime thinly sliced for garnish


  • ½ pint heavy cream well chilled
  • 2 tablespoons sugar
  • 1 tablespoon Grand Marnier ® liqueur optional


  • Preheat oven to 350 degrees.
  • Combine cracker crumbs, melted butter and sugar in a small mixing bowl.
  • Press evenly into a 9-inch pie pan with hands or the back of a spoon.
  • Bake for 10 minutes or until lightly brown. Set aside to cool.
  • In a small mixing bowl, dissolve gelatin in cold water, stir, and set aside.
  • In a heavy saucepan, combine egg yolks and lime juice and stir over medium-low heat for 10 minutes or until slightly thick and very hot. Be careful not to bring to a full boil.
  • Add softened gelatin to lime juice mixture. Whisk well for 1 minute or until gelatin is dissolved.
  • To quickly cool mixture, place saucepan in a large bowl filled with ice.
  • When completely cool, gradually whisk in condensed milk, stirring until blended well and mixture become thick.
  • Spoon into graham cracker crust and spread evenly.
  • Cover filling with plastic wrap and refrigerate.
  • When ready to serve, top pie with fresh Grand Marnier ® Whipped Cream and lime slices.
  • In a stainless steel mixing bowl, combine cream, sugar and liqueur.
  • Whip with an electric mixer on high until cream holds peaks. Be careful not to over-whip cream or it will separate. Cream is properly whipped when you can drag a finger through it and a trough remains.
