Heat the oven to 180C/fan 160C/gas 4. Arrange the rhubarb pieces in a single layer on a baking tray, sprinkle over the sugar and drizzle the vanilla extract on top. Cover with foil and bake for 15-20 minutes or until soft. Cool.
To make the custard, put the star anise in a pan with the milk and double cream, and bring slowly to the boil. Meanwhile, whisk the yolks, sugar and cornflour in a bowl until pale and creamy. Slowly add the hot cream mixture, whisking continuously. Return to the pan and cook over a low heat, stirring, for 8-10 minutes, or until the custard has thickened to the consistency of softly whipped double cream.
Strain the custard into a bowl. Put some clingfilm on the surface to prevent a skin forming, and chill.
Turn up the oven to 200C/fan 180C/gas 6. Using a 25cm plate as a template, cut out a circle in the puff pastry. Put on a baking tray and score a border 1-2cm from the edge. Prick inside the border with a fork then brush all over with beaten egg.
Bake for 20-25 minutes or until golden and cooked through. Gently push down the middle of the pastry to make a well for the custard. Leave to cool completely.
Assemble the tart when you are ready to serve. Put the tart case onto a serving plate. Spread the custard across the bottom of the case and finish with the rhubarb piled on top.
