- 1 1/2 cups fine graham cracker crumbs
- 1/2 cup sugar
- 1/2 stick (1/4 cup) butter, melted
- One 14-ounce can sweetened condensed milk
- 1/2 cup fresh lemon juice (about 2 large lemons)
- 1 teaspoon grated lemon zest
- 3 large egg yolks, whites reserved for meringue
- 3 large egg whites
- 1/4 teaspoon cream of tartar
- 1/4 cup sugar
Preheat oven to 325 degrees F.
For the filling: In a medium bowl, mix the condensed milk, lemon juice, zest and egg yolks, reserving the whites for the meringue. Pour the mixture into the crust.
For the meringue: Beat the egg whites and cream of tartar in a medium bowl with an electric mixer until soft peaks form, then add the sugar and whip until peaks are stiff.
Spread the meringue over the pie and seal to the edge of the crust. Bake until the meringue browns slightly, 15 to 20 minutes. Chill for at least 2 hours before serving.
