Skipjack's Key Lime Pie

Source: Skipjack's, Boston, Massachusetts

1 cup graham cracker crumbs
1/4 cup unsalted butter, melted
4 egg yolks
1 (14 ounce) can sweetened condensed milk
1/3 cup Key lime juice
1/3 cup sour cream

Whipped cream, toasted coconut, or raspberry sauce (optional garnishes)

In a large bowl combine the graham cracker crumbs and butter. Press evenly on the bottom and sides of an 8-inch pie plate. Chill while preparing the filling.

Heat oven to 325 degrees F.

In a mixing bowl beat the egg yolks until thick and pale yellow, 7 to 10 minutes. Add the milk, lime juice and sour cream and beat until blended and smooth. Pour into the crust and bake for 17 minutes or until the center feels set when lightly touched. Cool on rack. Chill. Garnish as desired.

Serves 6 to 8.
