Ingredients
- 1½ cups graham cracker crumbs
- 3 tbsp granulated sugar
- 6 tbsp unsalted butter, melted
- 4 large egg yolks
- 1 tbsp grated Key lime zest
- 14 oz sweetened condensed milk
- ½ cup fresh Key lime juice
- 1 cup heavy cream
- 2 tbsp powdered sugar
Method
- Heat the oven to 350°F. Mix the cracker crumbs, sugar and melted butter and press firmly into a 9-inch pie plate.
- Bake the crust until fragrant and lightly browned, about 10 minutes, then let it cool a little.
- Whisk the egg yolks and zest until pale, then whisk in the condensed milk and lime juice until smooth and slightly thickened.
- Pour into the crust and bake until the center just sets, 15 to 17 minutes; the filling should reach 160°F.
- Cool on a rack, then refrigerate at least 3 hours.
- Whip the cream with the powdered sugar to soft peaks and spread it over the pie before serving.
Notes
Bottled Key lime juice works when fresh Key limes are hard to find; regular limes make a sharper, less floral pie.
