4 egg yolks
1/4 cup sugar
1 cup whipping (heavy) cream
1 cup white baking chips
1 1/2 cups whipping (heavy) cream

Chocolate curls, if desired
1.    Beat egg yolks in small bowl with electric mixer on high speed about 3 minutes or until thick and lemon colored. Gradually beat in sugar.
2.    Heat 1 cup whipping cream in 2-quart saucepan over medium heat just until hot. Gradually stir at least half of the cream into egg yolk mixture, then stir back into hot cream in saucepan. Cook over low heat about 5 minutes, stirring constantly, until mixture thickens (do not boil).
3.    Stir in baking chips until melted. Cover and refrigerate about 2 hours, stirring occasionally, just until chilled.
4.    Beat 1 1/2 cups whipping cream in chilled medium bowl with electric mixer on high speed until stiff. Fold refrigerated mixture into whipped cream. Spoon mixture into parfait or wine glasses. Garnish with chocolate curls. Store covered in refrigerator.
