(1) With a graham cracker crust (adapted from Food Network):
1/3 of 1-lb. box graham crackers, broken into pieces
5 T. melted unsalted butter
1/3 c. sugar
3 egg yolks
2 t. lime zest
14 oz. sweetened condensed milk
2/3 c. freshly squeezed Key lime juice
1 c. heavy cream, chilled
2 T. confectioners' sugar
Preheat oven to 350 F.
Place graham crackers in food processor, and process to crumbs.
Add melted butter and sugar, and pulse to combine.
Press into bottom and up sides of a 9-in. pie pan, forming a neat border.
Bake until set and golden, about 8 minutes.
Set aside on a wire rack, leaving oven on.
Meanwhile, in an electric mixer with the wire whisk attachment, beat egg yolks and lime zest at high speed until very fluffy, about 5 minutes.
Gradually add condensed milk, and continue to beat until thick, 3 - 4 minutes. Lower mixer speed, and slowly add lime juice, mixing just until combined.
Pour into prepared crust.
Bake for 10 minutes, or until filling has just set.
Cool on a wire rack, then refrigerate.
Freeze for 15 - 20 minutes before serving.
Whip cream and confectioners' sugar until nearly stiff.
Cut pie into wedges, and serve very cold, topping each wedge with a dollop of whipped cream.
