Equipment

  • Mixing bowl
  • Hand or stand mixer
  • Zester

Ingredients

  • 1 pre-packaged graham cracker crust
  • 4 egg yolks
  • 1 can (14 oz) sweetened condensed milk
  • ½ cup lime juice concentrate

Instructions

  • Preheat the oven to 325 degrees.
  • Whip the egg yolks at high speed until fluffy, about 5 - 6 minutes. Slowly add the sweetened condensed milk. Continue to whip until thick, about 3 - 4 minutes. On low speed, slowly add the lime juice concentrate just until blended.
  • Pour the mixture into a pre-packaged graham cracker crust and bake for 15 minutes, or until the filling has just set.
  • Cool the key lime pie on a wire rack for about 30 minutes and then refrigerate until completely cooled. Top with sliced limes and whipped cream, if desired.

Notes

  1. Place the graham cracker crust on a baking sheet before baking to make it easier to get the pie in and out of the oven.
  2. When the key lime pie is ready to be removed from the oven, it should be slightly firm to the touch. The pie filling will continue to firm up as it cools. It will also become firmer during refrigeration.
