Icing
Method
1.Preheat oven to very hot, 220°C. Line 2 oven trays with baking paper.
2.Place 1 pastry sheet on each tray. Bake for 20 minutes or until pastry puffs and browns. Cover pastry with a clean tea towel and gently flatten. Set aside to cool.
3.Lightly grease a 23cm square cake pan. Line base and sides with foil. Place 1 pastry sheet, flat-side down, in base of prepared pan.
4.Bring milk and cream to the boil in a saucepan. Whisk egg-yolks, sugar, flour and cornflour in a heatproof bowl until thick and pale. Gradually whisk hot milk mixture into egg mixture.
5.Transfer to a clean saucepan. Stir over low heat for 5-6 minutes until custard comes to the boil and thickens. Reduce heat and simmer for 30 seconds.
6.Remove from heat. Stir in butter and vanilla. Pour over pastry and place remaining pastry flat-side up on top. Chill for 1 1/2 hours, until firm.
7.Meanwhile to make icing; combine icing sugar and passionfruit pulp in a bowl until smooth. Turn slice out onto a large chopping board and remove the foil. Spread icing over. Set aside until icing is set. Use a serrated knife to cut the vanilla slice into 16 pieces.
