Remove from heat. Cover and let stand for 15 minutes to infuse cream with vanilla flavor. Remove vanilla bean; discard or reserve for another use.
Meanwhile, in a medium bowl mix egg yolks and sugar. Beat with a wire whisk just until mixture is thick and lemon colored. Gradually whisk warm cream into egg mixture.
