Pastel de Nata with Shatteringly Flaky Pastry, Cinnamon-Dusted Custard and Caramelized Top

Make the rough puff pastry: mix flour and salt. Add grated frozen butter and toss to coat each piece in flour. Add ice water and mix minimally — the dough should be shaggy, with visible butter flakes throughout. Do not overwork. Turn onto a floured surface and gently press into a rough rectangle. Roll to about 40x20cm. Fold into thirds like a letter. Rotate 90 degrees. Roll out again and fold again. Repeat one more time. Wrap and refrigerate for 30 minutes. This lamination creates the hundreds of thin flaky layers that characterize the original pastry from the Jerónimos Monastery in Belém.

Ingredients

• For the rough puff pastry (massa folhada):
• 200g (1.75 cups) all-purpose flour
• 1/2 tsp fine salt
• 120ml (1/2 cup) ice-cold water
• 150g (10.5 tbsp) cold unsalted butter, grated on a box grater and kept chilled
• For the custard filling (creme de pastel):
• 250ml (1 cup) whole milk
• 200ml (3/4 cup) heavy cream
• 200g (1 cup) granulated sugar
• 60ml (1/4 cup) water
• 1 cinnamon stick
• Peel of 1 lemon, removed in wide strips
• 5 egg yolks plus 1 whole egg
• 30g (3.5 tbsp) all-purpose flour
• 1/4 tsp vanilla extract
• For finishing:
• Ground cinnamon and powdered sugar for dusting at the table
• Special equipment: a standard muffin tin (12 cups)

Instructions

1. Make the rough puff pastry: mix flour and salt. Add grated frozen butter and toss to coat each piece in flour. Add ice water and mix minimally — the dough should be shaggy, with visible butter flakes throughout. Do not overwork. Turn onto a floured surface and gently press into a rough rectangle. Roll to about 40x20cm. Fold into thirds like a letter. Rotate 90 degrees. Roll out again and fold again. Repeat one more time. Wrap and refrigerate for 30 minutes. This lamination creates the hundreds of thin flaky layers that characterize the original pastry from the Jerónimos Monastery in Belém.
2. Make the syrup: combine sugar, water, cinnamon stick, and lemon peel in a small saucepan. Bring to a boil without stirring and cook until the sugar dissolves and the syrup reaches 100°C (212°F) — about 3 minutes. Do not allow it to caramelize. Remove cinnamon and lemon peel. The infused syrup carries the fragrance of Lisbon pastry shops into the custard.
3. Make the custard base: whisk flour into a small amount of the cold milk to form a lump-free paste. In a saucepan, combine remaining milk and cream. Heat until just below boiling. Whisk the hot milk into the flour paste gradually to temper it. Return to the pan and cook over medium heat, whisking constantly, until thickened to a very thick béchamel. Remove from heat.
4. Add the egg yolks: whisk egg yolks and the whole egg together. Slowly pour the hot sugar syrup into the custard base, stirring constantly to combine. Add the egg mixture and vanilla, whisking until completely smooth and uniform. The custard should be pourable — thinner than you expect. It will set in the oven. Strain through a fine sieve to remove any cooked egg bits. Cool to room temperature.
5. Shape the pastry cases: preheat oven to its maximum temperature — at least 250°C (480°F) ideally higher. Pastel de nata are baked at extreme heat; this is how the tops caramelize. On a lightly floured surface, roll the chilled pastry into a thin rectangle. Tightly roll it lengthwise into a log. Slice the log into 12 equal discs. Place one disc cut-side down in each muffin cup. Dip your thumb in cold water and press down into the center of the disc, spreading it up and out to form a cup with thin walls and base. The sides should extend just above the tin rim.
6. Fill and bake: ladle custard into each pastry case to about 3/4 full — the custard will puff slightly. Do not fill to the brim. Bake at maximum heat for 12-15 minutes. Watch carefully — the tops should develop dark amber-to-black caramelized spots and even slight scorching. This burnt caramelization is the signature of the authentic pastel. If they are uniformly pale golden, the oven was not hot enough.
7. Cool briefly: remove from oven. The custard will be bubbling and very soft — it firms as it cools. Let sit for 5-10 minutes before removing from the tin. The pastry should be shatteringly flaky when tapped with a fingernail.
8. Serve warm, dusted generously with ground cinnamon and powdered sugar at the table — dusting at the table is the Portuguese tradition. Pastel de nata originated at the Mosteiro dos Jerónimos in Belém around 1837, made by monks from surplus egg yolks left over from starching habits. The original recipe has never been fully published. The pastelaria at Belém makes 20,000 per day — the most visited food destination in Portugal.
