Basque Sweet Temptation: Pastel de Nata (Basque-style Portuguese Custard Tart)

Instructions

1. Preheat the oven to 220°C (425°F).
2. Roll out the puff pastry and cut it into 12 circles to fit the tart molds. Line the molds with the pastry and chill in the refrigerator while preparing the custard.
3. In a saucepan, heat the milk with the cinnamon stick and lemon peel until it almost reaches a boil. Remove from heat and let it infuse for 15 minutes.
4. In a bowl, whisk together the sugar and flour. Add the egg yolks and whisk until smooth.
5. Remove the cinnamon stick and lemon peel from the milk. Gradually pour the milk into the egg mixture, whisking constantly.
6. Strain the custard back into the saucepan and cook over low heat, stirring constantly, until it thickens. Stir in the vanilla extract.
7. Pour the custard into the prepared tart molds and bake for 15-20 minutes, or until the pastry is golden and the custard is set.
8. Remove from the oven and let the tarts cool before serving.
