Lilikoi Vanilla Slice
2 sheets puff pastry
Passionfruit vanilla custard
1/4 cup caster sugar
2/3 cup cornflour
3 1/4 cups milk
1/2 cup passionfruit juice (see note below)
1 vanilla bean, seeds scraped
2 egg yolks
3 Tablespoons butter, softened
3/4 Cup powdered sugar, sieved
pulp of 2 passionfruit
Note: To make passionfruit juice, blend passionfruit pulp in a food processor to crack seeds. Strain through a fine sieve. To get 1 cup of juice, you will need about 12 passionfruit.
Preheat oven to 375° . Trim each to 7" square, prick all over with a fork and bake for 15 minutes until puffed and golden. Cool on a wire rack, then halve each sheet horizontally with a serrated knife to give four squares.
For the custard, combine the sugar and cornflour in a saucepan. Over medium heat, add milk a little at a time, whisking until smooth. Add juice and vanilla seeds. Bring just to the boil, stir continuously with a wooden spoon until smooth and thick. Makes sure you get into those corners. Remove from heat and whisk in yolks and butter. Set aside.
Line a 7" square cake pan with baking paper. Place a piece of pastry at the bottom and pour over a third of the custard. Level and top with another piece of pastry. Repeat with remaining custard and pastry. Chill until set.
For icing, combine ingredients in a bowl and mix. Spread over slice and serve.
