Classic Key Lime Pie


Serves 8

    Issue 123

This classic pie includes a flaky pastry crust, billowy whipped-cream topping, and of course a silky, aromatic sweet-tart custard filling. If you can’t find fresh Key limes, you can substitute common lime juice, which will be tart but without the floral notes found in Key limes. Bottled Key lime juice is an even better choice as long as it’s 100% juice. The pie needs to chill for at least 5 hours before serving.

For the crust
  • 4-1/2 oz. (1 cup) unbleached all-purpose flour; more as needed
  • 1-1/3 oz. (1/3 cup) cake flour
  • 1 tsp. granulated sugar
  • 1/4 tsp. table salt
  • 4 oz. (1/2 cup) cold unsalted butter, cut into 8 pieces
  • 1/4 cup ice-cold water
  • 1 tsp. cider vinegar
For the filling and topping
  • 4 large egg yolks
  • 1 14-oz. can sweetened condensed milk
  • 1/2 cup fresh Key lime juice (from 14 to 16 limes) or bottled Key lime juice (preferably Manhattan brand)
  • 1-1/2 cups cold heavy cream
  • 1 oz. (1/4 cup) confectioners’ sugar
  • 3/4 tsp. pure vanilla extract
Make the crust

In a food processor, pulse the flours, sugar, and salt to combine. Add the butter and begin cutting it into smaller pieces with four 1-second pulses.

In a small bowl, combine the water and vinegar. While pulsing, gradually add the liquid in a thin stream through the feed tube until the dough forms several large clumps, 20 to 30 pulses. The butter should still be visible in small pieces.

Gather and press the dough into a 1-inch-thick disk. Wrap in plastic and refrigerate for at least 1 hour.

Dust a work surface and both sides of the dough lightly with flour. Flatten the dough slightly by tapping it all over with a rolling pin, then roll the dough out into a 12-inch circle. Try to make the circle as even as possible, but don’t be concerned about rough edges.

Roll the dough around the rolling pin and carefully unroll over a 9-inch glass or metal pie plate. Gently press it into the bottom and up the sides of the pan without stretching it. With scissors, trim the overhanging dough to 1/2 inch beyond the rim of the plate. Fold the overhang under and crimp decoratively. Wrap the crust in plastic and refrigerate for at least 1 hour.

Position a rack in the center of the oven and heat the oven to 400°F.

Line the crust with aluminum foil and fill with dried beans or pie weights. Put the crust on a rimmed baking sheet and bake until the edge is firm and pale golden, 20 to 25 minutes. Carefully remove the foil and beans. Prick the bottom of the crust all over with a fork. Continue baking until golden-brown, 8 to 12 minutes. (If the pastry puffs up, gently prick it with a toothpick.) Transfer to a wire rack and cool to room temperature.

Fill and bake the pie

Reduce the oven temperature to 350°F.

In a medium bowl, vigorously whisk the egg yolks by hand until slightly thickened, about 1 minute. Gently whisk in the sweetened condensed milk until combined, then whisk in the lime juice; the filling will thicken just a bit. Scrape the filling into the crust and spread it evenly.

Bake on a rimmed baking sheet for 20 minutes—the filling will be only partially set. Cool to room temperature on a rack, then refrigerate until the filling is completely set, at least 5 hours.

Top the pie

Chill a metal bowl and the beater(s) of an electric mixer. In the chilled bowl, combine the cream, confectioners’ sugar, and vanilla. Beat on medium-high speed to firm peaks. Spoon the cream over the filling, swirling it attractively. Slice and serve.

Make Ahead Tips

The dough can be made up to 24 hours ahead of shaping. Refrigerate, wrapped in plastic.

The crust can be shaped up to 24 hours ahead of baking. Refrigerate, wrapped in plastic.

You can fill, bake and chill the pie (but don't top with whipped cream) up to 1 day ahead; if refrigerating for more than 5 hours, cover the pie with plastic wrap. Top the pie when you’re ready to serve.

I made this last yearwhen the recipe was published. I did use a Graham cracker crust, and wished I had gone with a pastry crust. I forgot where the recipe originated. Greg Patent lives in Missoula, Mt, and I spent hours today combing saved recipes from him before finding it. The recipe is so good, it was worth the time and effort to find it! It is a real pain to juice fresh Key limes, but once that is accomplished, the pie is very quick and easy to make. And totally delicious!

I used this filling this last night with a graham cracker crust and a spoonful of whipped cream and it was fantastic! Not too sweet- a perfect balance... Being a New Englander I can not comment on the "classic" debate... but can attest that it is delicious!

also being raised in Fla., Key West, specifically, The original Key Lime Pie originated in Key Largo, 1969, @Parrot Joe's/Jack's, and MOST CERTAINLY DID have a flake crust, not graham cracker. And No merangue, or cool whip either!! Sorry to dispute your word jfk66!!!cm

Get a graham cracker crust. Mix the egg yolks, sweetened condensed milk, and lime juice (preferably Mrs. Biddle's or Nellie and Joe's) and don't bake. The lime juice is of higher acidity than regular lime juice and is sufficient to cook the eggs. Skip the Whipped cream. Keep it simple.

Well that's funny because I also grew up in Florida and I've always had key lime pie with a crust. This recipe was excellent-really nice balance of tang/tart/sweet

As someone who grew up in southern Florida, I can say key lime pie does NOT have a pastry crust. What I love about it is the crumb crust. I don't know about the filling but the whole thing is a fluffed up version of a folk dessert that developed because of the lack of refrigeration. I'm more of a purist. I hate to give it a rating since I haven't made it but the review function makes me.

Smooth, creamy, and just the right balance of tangy and sweet-- a great dessert and easy too.
