The History of Pastel de Nata: From Belém Monastery to Brussels
Some pastries transcend simple pleasure to become true cultural symbols. The Pastel de Nata is one of them. This small caramelised egg custard tart, crispy and golden, tells the entire story of Portugal — its monasteries, spices, explorers, and passion for intense flavours.
At Wooly Pâtisserie, we've been making our Pastéis de Nata fresh every morning in our Brussels kitchen since 2015. This guide takes you to the origins of this global pastry icon.
1837: The Birth of a Legend in Belém
The story begins on the banks of the Tagus river in the Belém neighbourhood of Lisbon. The Mosteiro dos Jerónimos, a UNESCO World Heritage masterpiece of Manueline architecture, housed monks who kept a secret culinary tradition.
Like all Portuguese convents of the era, the Hieronymite monks used egg whites to starch their religious garments. This left a constant surplus of golden egg yolks, which they transformed into sweet pastries — a tradition that created an entire repertoire of Portuguese egg-based sweets: Pastéis de Tentugal, Queijadas, Barquinhos de Aveiro, and of course, the Pastel de Nata.
In 1834, liberal reforms dissolved Portugal's religious orders. The Hieronymite monks, forced to leave their monastery, partnered with a local merchant to sell their recipes. In 1837, Pastéis de Belém opened at number 84 Rua de Belém — and has never closed since.
The Secret Known to Only Three People
The original recipe is one of the world's best-kept culinary secrets, known only to three people, passed down across generations. Pastry makers who work in the "oficina do segredo" (the secret workshop) sign confidentiality agreements. The shop produces between 10,000 and 20,000 pastéis daily — up to 40,000 on weekends.
Pastel de Belém vs Pastel de Nata: What's the Difference?
The Pastel de Belém is the original, legally protected recipe exclusive to the Belém shop. The Pastel de Nata is the universal "free" version found throughout Portugal and the world. Differences are subtle — custard texture, pastry fineness, caramelisation level. Neither is objectively "better"; quality of execution and freshness are what truly matter.
The Portuguese Conventual Pastry Tradition
Portugal boasts over 200 conventual pastry recipes, each linked to a specific region, convent, or liturgical season — all characterised by their richness in egg yolks, sugar, and almonds. The most celebrated include Pastel de Tentugal (Coimbra), Queijadas de Sintra, Barquinhos de Aveiro, and Ovos Moles.
How to Recognise an Excellent Pastel de Nata
The puff pastry: Ultra-thin, crispy, lightly caramelised on the edges with distinct layers. Soft or crumbling pastry indicates poor quality or incorrect reheating.
The custard: Silky texture, slightly wobbly when gently shaken, ivory to golden in colour with characteristic brown caramelisation spots — these are not defects, they are the signature of a well-baked tart!
Baking temperature: A true Pastel de Nata is baked at 230-250°C for 10-12 minutes. This intense heat creates the magic: the puff pastry caramelises and the custard develops those characteristic lightly roasted flavours.
Freshness: A Pastel de Nata is at its peak straight from the oven, still warm. At Wooly, we bake multiple times daily — never reheated day-old pastry.

How to Enjoy Pastel de Nata the Portuguese Way
In Lisbon, the ritual is sacred: eaten warm, dusted with cinnamon and icing sugar, standing at the counter with a café (espresso). At Wooly Brussels, we recommend reheating 8-10 minutes at 180°C and pairing with an espresso or a lightly chilled glass of Vinho Verde.
