Sonia did this,and it looks so yummy.And, yes indeed so yummy!...I used homemade puff pastry, it's very crispy,and the sweetness are just right.And, it's easy to make.Here's the recipe I copied and modified a bit from Sonia.
Puff pastry from freezer, thaw and roll in 2 -3 mm thick.Cut into square.
240 gm hot water
90 gm coarse sugar
1/2 vanilla essence
1/4 tsp white vinegar
Dissolved sugar in hot water,set aside to cool.
Break eggs in a mixing bowl, lightly stir.
Add in syrup (no1),vanilla essence and vinegar.lightly stir well to combine.
Strain the mixture twice, and set aside.
Arrange the square puff pastry in a muffin pan or small tarts mould.
Pour egg custard filling in the puff pastry,about 80-90 % full.
Bake in pre-heated oven at 180 C for 35 minutes or till golden brown.
Remove from oven and leave to cool.
