½cupfresh lime juiceI use Persian limes, but you can use key limes.
1tspfresh lime zest
Topping:
½cupheavy cream
3Tbsppowdered sugar
¼tspvanilla extract
Instructions
For the crust, pulverize the graham crackers in a food processor until they are finely ground. Stir in the melted butter.
Press the crumbs up the sides and on the bottom of a 9-inch pie plate. Chill while you prepare the filling.
For the filling, beat the cream in a large bowl until stiff peaks form. Set aside. Whisk together the sweetened condensed milk and lime juice. Fold in the whipped cream and lime zest.
Spread the filling into the crust. Chill for 3-4 hours, or until set. It can also be made a day or two ahead.
For the topping, beat the cream until soft peaks form. Add the powdered sugar and vanilla and beat again until stiff peaks form.
To serve, cut the pie into slices and top each slice with whipped cream. I like to garnish with a tiny slice of fresh lime.
Notes
The cream will whip up faster if you first chill the bowl and beaters in the freezer for about 10 minutes.
Store any leftover pie in the refrigerator for up to 5 days. You can also freeze the pie and serve it frozen.
