Ingredients
Pastry
- 1 sheet frozen puff pastry, thawed
- Flour for dusting
Custard Filling
- 3/4 cup (150g) granulated sugar
- 1/3 cup (40g) all-purpose flour
- 1 1/4 cups (300ml) whole milk
- 1 cinnamon stick
- Peel from 1 lemon (use a vegetable peeler to avoid the bitter white pith)
- 6 large egg yolks
- Ground cinnamon and powdered sugar for dusting (optional)
Instructions
- Prepare the pastry: Roll out the thawed puff pastry sheet on a lightly floured surface into a thin rectangle. Roll it up tightly from one short end to the other like a jelly roll, then slice into 12 equal pieces.
- Shape the tart shells: Place each rolled pastry piece cut-side down into muffin tin cups. Using your thumbs, press and stretch the dough evenly to cover the base and sides of each cup.
- Make the custard base: In a saucepan, whisk together the sugar, flour, and a small portion of milk to form a smooth paste. Add the remaining milk along with the cinnamon stick and lemon peel. Cook over medium heat, whisking constantly until the mixture simmers and thickens.
- Infuse flavors: Remove the saucepan from heat and allow the milk mixture to steep with the cinnamon stick and lemon peel for 10 minutes to deepen the flavors.
- Combine custard ingredients: Whisk the egg yolks in a separate bowl. Remove the lemon peel and cinnamon stick from the milk mixture, then gradually whisk the warm milk mixture into the egg yolks to avoid curdling.
- Strain and cool custard: Strain the combined custard through a fine mesh sieve to ensure smoothness and let it cool slightly before filling the pastry shells.
- Preheat the oven: Preheat your oven to 500°F (260°C) or as high as it can safely go for the best caramelization.
- Fill and bake: Pour the custard filling into each pastry cup about three-quarters full. Bake the tarts for 12 to 15 minutes, until the custard puffs up and the tops blister and turn golden brown with characteristic blackened spots.
- Cool and serve: Allow the tarts to cool in the tin for 5 minutes before transferring them to a wire rack. Optionally, dust with ground cinnamon and powdered sugar before serving.
Notes
- Use frozen puff pastry that is well-thawed for best results when shaping tart shells.
- The lemon peel should be free of white pith to prevent bitterness in the custard.
- High oven temperatures help achieve the classic blistered, slightly charred top traditional to Portuguese custard tarts.
- Adjust baking time based on your oven to avoid burning while ensuring a creamy custard inside and a crisp pastry outside.
- Serve warm or at room temperature for the best flavor and texture.
