9 inch pie shell, baked
2 egg yolks, lightly beaten
1 (14 oz.) can sweetened condensed milk
1/2 c. fresh lime juice
1 c. heavy cream
2 tbsp. confectioners' sugar, sifted

Beat egg yolks with condensed milk just until blended. Add lime juice and beat until mixture thickens slightly. Pour into baked and cooled pie shell. Refrigerate until well chilled. Whip cream and fold in sugar. Spread over pie filling, making sure whipped cream touches pastry all around. Return to refrigerator and chill several hours or overnight before serving.
