Remove vanilla bean from the milk and slowly pour over the egg yolk mixture, whisking all the time. Return to the saucepan and cook over a low heat and whisk constantly until the mixture thickens. Transfer mixture into a bowl, cover and chill. Whip ricotta and stir through crème anglaise before assembling the parfaits.
