Frosty Lime Pie

Frosty Lime Pie

This frozen dessert delivers cold, tart relief on a hot summer day. The real secret to making this pie, is in how you handle the egg yolks. Heat them too much and they scramble, or too little and they won’t thicken. When the yolks get too hot for your finger, around 165 degrees, they’re hot enough.


For the graham cracker crust:

  • 1 ¼cups graham cracker crumbs
  • ¼cup superfine sugar
  • Pinch of salt
  • ¼cup unsalted butter, at room temperature

For the filling:

  • 5eggs, separated
  • ¾cup superfine sugar
  • ⅔cup fresh squeezed, strained lime juice
  • 2teaspoons grated lime zest
  • ⅛teaspoon salt

For the topping:

  • 1 ½cups heavy cream, whipped
  • Thin slices of lime or fresh strawberries
  • Sugar


  1. Heat oven to 350 degrees.
  2. Make the crust: Place the graham cracker crumbs, sugar and salt in a bowl. Add the butter and work with a wooden spoon (or your fingers) to blend well. Press the mixture evenly into a 9-inch pie plate with your fingertips, or use an 8-inch pie plate to press down the mixture. Transfer to oven and bake 10 minutes. Cool to room temperature.
  3. Make the filling: Beat the yolks in the bowl of a stand mixer until very thick. Gradually beat in half the sugar until mixture is very pale and thick and forms a rope when dropped from the beater.
  4. Stir in the lime juice and zest and transfer to a double boiler. Heat over over simmering water, stirring until mixture coats the back of a spoon. Do not allow to boil. Transfer to a large bowl and let cool to room temperature.
  5. Once the yolk mixture reaches room temperature, beat the egg whites with the salt in a separate bowl until soft peaks form. Gradually beat in the remaining sugar until mixture is stiff and shiny. Stir a third of this meringue mixture into the cooled yolk mixture. Fold in remaining meringue mixture until evenly distributed.
  6. Turn the mixture out into the cooled graham cracker pie shell and bake 15 minutes, or until lightly tinged with brown. Let cool.
  7. Transfer the pie to the refrigerator and let chill thoroughly, uncovered, then transfer to the freezer. Once it is frozen, cover with plastic wrap and keep frozen until just before serving.
  8. Remove from the freezer 10 minutes before serving. Cover with the whipped cream and garnish with lime slices dipped in sugar or fresh strawberries.


  • Pie will keep frozen two to three weeks. If a less tart pie is desired, cut down the lime juice to one-half cup. Extra pie can be refrozen. If desired, pie can be well chilled and served without freezing.
