Sugar-Free Pastel de Nata (Portuguese Egg Tart)

Steps

1. 1
   Combine vanilla custard powder with milk and mix thoroughly.
2. 2
   Add the sugar substitute (Sugar Free Natura) for sweetness instead of regular sugar.
3. 3
   Cook the mixture over heat while stirring continuously until it thickens into a smooth, lump-free custard.
4. 4
   Roll out the puff pastry, shape it into a roll, and pinch the edges so it doesn't unravel.
5. 5
   Cut the rolled pastry into pieces, place them into tart molds, and press the pastry up the sides to form a cup shape.
6. 6
   Preheat the oven to a very high temperature of 240-250°C.
7. 7
   Pour the cooked custard into each pastry shell, filling but not overfilling.
8. 8
   Bake in the preheated high-temperature oven until the pastry is crisp and the custard top is slightly caramelized/burnt in spots.
9. 9
   Let cool slightly before serving; best enjoyed while still warm.
