Make Créme Anglaise. In 2-quart saucepan, heat cream and vanilla bean (if using vanilla, add at the end) just to boiling over low heat. In small bowl, beat egg yolks and sugar with wire whisk. Beat small amount of hot cream into yolks. Blend yolk mixture into cream in saucepan; cook over low heat about 10 minutes, stirring constantly, until custard coats a spoon. DO NOT BOIL. Remove from heat. Remove vanilla bean and scrape seeds into sauce. Stir until seeds separate. Cool to room temperature, about 30 minutes. Refrigerate until serving time.
