Why the Macau Egg Tart Was Invented by a British Pharmacist (October 2026)

Macau’s most famous edible export was not created by a Portuguese baker, a Chinese pastry chef, or a Macanese grandmother with generations of family recipes. It was invented by a British pharmacist from Essex who had never baked professionally in his life.

His name was Andrew Stow. In 1989, he opened a small bakery in Coloane Village and started selling a custard tart that would eventually redefine how the world thinks about Macau food. Today, that bakery produces between 13,000 and 14,000 tarts every single day, and the queues outside its doors never seem to shrink.

As someone who has spent years documenting Macau’s people and places, I find this story irresistible. The BBC even referenced my book, Macao – People and Places, Past and Present, when they wrote about Andrew Stow and Lord Stow’s Bakery. The story of how a pharmacist’s precision met a Portuguese monk’s recipe and produced Macau’s signature pastry is one of the great accidental food origin stories of our time.

Let me walk you through why the Macau egg tart was invented by a British pharmacist, how Andrew Stow’s scientific background shaped the recipe, and what makes this pastry unlike anything else in the world.

The Short Answer

The Macau egg tart (known locally as pou tat) was created in 1989 by Andrew Stow, a British industrial pharmacist who moved to Macau in 1979 to work for Anglo French Laboratories. After discovering Portuguese pastel de nata through a chef friend at the Hyatt Regency Macau, Stow experimented with the recipe at his Coloane Village bakery, Lord Stow’s Bakery. He combined the flaky Portuguese puff pastry shell with a creamier English-style custard, removed the corn flour used in traditional Portuguese versions, and created a caramelized top similar to crème brûlée. The result was a Portuguese-English hybrid that neither community expected and both eventually embraced.

Who Was Andrew Stow? From Essex Pharmacist to Macau Baker

Andrew Stow grew up in Essex, England, far from the sun-drenched harbors of southern China. He trained as an industrial pharmacist, a career path that required exact measurements, systematic thinking, and a deep understanding of how ingredients interact under different conditions. None of this screamed “future pastry legend.”

His early career took him to Boots, the British pharmacy chain where many UK pharmacists cut their teeth. At Boots, Stow developed the methodical, almost obsessive approach to quality control that would later define his baking. He learned to think in terms of ratios, reactions, and reproducibility. He learned that changing one variable could transform an entire product.

Industrial pharmacy is a specific discipline within pharmaceutical science. Unlike community pharmacists who dispense medications, industrial pharmacists work on the formulation and manufacturing side. They develop the actual products: deciding on ingredients, determining dosages, testing stability, and ensuring that every batch meets exact specifications. It is essentially applied chemistry with a production focus. This is the training Andrew Stow brought to baking.

In 1979, Stow accepted a position with Anglo French Laboratories and moved to Macau. At the time, Macau was still a Portuguese territory (it would not return to Chinese sovereignty until 1999). The city had a significant Portuguese expatriate community, a growing economy, and a food scene that reflected its 400-plus years as a colonial crossroads between East and West.

Why did a pharmacist leave pharmaceuticals for baking? The transition was not sudden. During his years in Macau, Stow became deeply embedded in the local food culture. He was a regular at restaurants and hotel kitchens, always curious about how dishes were made and whether they could be made differently. His sister Eileen has noted that Andrew was always cooking, always experimenting, always bringing new ideas into the kitchen. The bakery was less a career change than a natural extension of an obsession that had been building for years.

Stow’s sister, Eileen Stow, later described him as a “six-year-old in an adult body” when it came to the kitchen. He was fearless. He experimented constantly. He was the kind of person who would taste something at a restaurant, go home, and spend weeks trying to reverse-engineer it. His pharmacist brain treated recipes like formulas to be optimized.

This combination of scientific training and culinary fearlessness is essential to understanding why Andrew Stow, of all people, created Macau’s most iconic pastry. He was not a trained baker. He was a trained problem-solver who happened to love food and happened to live in a place where two great pastry traditions collided.

The Portuguese Egg Tart: A History That Started With Monks

To understand why the Macau egg tart British pharmacist story matters, you have to understand the pastry Andrew Stow was working from. The Portuguese egg tart, or pastel de nata, has one of the most fascinating origin stories in European food history.

Back in the 13th century, Catholic monks at the Jerónimos Monastery in the Belém district of Lisbon used egg whites to starch their clothing and altar cloths. Nuns in convents across Portugal did the same. This left them with a massive surplus of egg yolks and a creative problem: what do you do with hundreds of leftover yolks every week?

The answer, apparently, was pastry. Portuguese monks and nuns developed an entire tradition of egg-yolk-based sweets, many of which still exist today. The pastel de nata was one of the most successful. It featured a flaky, hand-moulded puff pastry shell filled with a rich egg custard and baked until the top caramelized into dark, slightly bitter spots.

This monastic baking tradition was remarkably productive. Portuguese convent sweets, known as doçaria conventual, include dozens of recipes that originated in monasteries and convents across the country. Many are named after the religious institutions that created them. The pastel de nata from Belém is simply the most famous of a vast and delicious family of egg-yolk-based desserts born from practical necessity and religious devotion.

After the religious orders were dissolved in Portugal in 1834, the Jerónimos Monastery began selling their pastéis de nata to generate revenue. In 1837, the recipe was sold to the nearby Fábrica de Pastéis de Belém, which still operates today and still uses the original 19th-century recipe, guarded as a closely held secret. Only a handful of master bakers know the complete formula, and they are bound by confidentiality agreements that have kept the recipe private for nearly two centuries.

In Belém, eating a warm pastel de nata with a shot of espresso became a cultural ritual. Millions of people make the pilgrimage to the Fábrica de Pastéis de Belém every year specifically for this experience. The combination of caffeine, caramelized sugar, creamy custard, and flaky pastry is one of the great simple pleasures in world food.

This is the tradition that eventually reached Macau through its Portuguese colonial connection. And this is the pastry that Andrew Stow encountered, fell in love with, and decided he could improve.

The Medieval English Custard Tart: The Other Half of the Story

But the Macau egg tart is not simply a Portuguese import. It is a hybrid, and the other half of that hybrid comes from England. This is the part most people miss, and it is central to understanding why a British pharmacist created something genuinely new rather than just copying an existing recipe.

Custard tarts have existed in England since at least the late medieval period. Historical records show that custard tarts, known variously as doucets or darioles, were served at the coronation of King Henry IV in 1399. These early English custard tarts used a shortcrust pastry shell and a filling made from eggs, cream, and sugar, sometimes flavored with cinnamon or other spices.

The English were serious about their custard. Medieval English cookbooks contain numerous recipes for custard-based dishes, and custard tarts were considered appropriate fare for royal occasions, not just everyday eating. The use of cream rather than milk gave English custard tarts a richness and smoothness that distinguished them from simpler egg-based desserts on the European continent.

English custard tarts evolved differently from their Portuguese cousins. They tended to be richer and creamier, with a smoother, more flowing custard that relied heavily on cream rather than just milk. They did not typically have the caramelized, blistered top that characterized the Portuguese version.

Andrew Stow grew up eating English custard tarts. When he encountered pastel de nata in Portugal, his English palate recognized both the brilliance of the Portuguese version and the potential for a different approach to the custard. His pharmacist brain saw variables that could be adjusted.

This is why the story is so compelling. Stow was not just an Englishman who liked Portuguese food. He was a scientifically trained Englishman who understood both custard traditions and had the precision and patience to combine them into something neither tradition had produced alone.

How Andrew Stow Invented the Macau Egg Tart

The actual invention of the Macau egg tart happened through a combination of accident, friendship, and pharmaceutical-grade experimentation. The story involves a hotel kitchen, a chef mentor, and a series of trips to Portugal that would transform Macau’s food landscape forever.

In the 1980s, the Hyatt Regency Macau on Coloane was experimenting with egg custard tarts for its guests. The hotel’s executive chef, an Austrian named Raimund Pichlmaier, had encountered pastel de nata in Portugal and was producing his own versions for the hotel. Pichlmaier and Stow became friends, and it was Pichlmaier who introduced Stow to the Portuguese tart in its authentic form.

Stow was hooked. He began making trips to Belém, just outside Lisbon, to study pastel de nata at its source. He tasted tarts from multiple bakeries. He talked to bakers. He observed techniques. He brought notes back to Macau and began experimenting in his own kitchen with the systematic approach of a pharmacist running clinical trials.

The key innovation was the custard. Traditional Portuguese pastel de nata uses corn flour (cornstarch) to thicken the custard, which gives it a slightly jelly-like consistency. Stow’s English palate preferred a creamier, more flowing custard, closer to the English custard tart tradition. So he removed the corn flour and adjusted the ratio of eggs, cream, and sugar to achieve a smoother, richer filling.

Removing the corn flour was not a trivial change. Corn flour serves as a stabilizer in baking, helping the custard set evenly and preventing it from splitting or curdling during high-temperature baking. Without it, the custard becomes more temperamental, more sensitive to oven temperature and baking time. Stow’s pharmaceutical training in formulation science was directly relevant here. He understood how to adjust other variables (egg ratio, cream content, sugar levels, baking temperature) to compensate for the removal of a key stabilizer while maintaining a consistent, reproducible result.

He kept the Portuguese puff pastry shell, which is made through a labor-intensive process of folding and rolling dough with butter to create dozens of delicate layers. Rather than using pre-made or machine-pressed shells, Stow insisted on hand-moulded pastry. The shells were gently pounded into shape, creating a texture that was simultaneously crisp and tender.

He also kept the caramelized top. This is the signature visual element of both the Portuguese and Macau egg tarts, those dark, blistered spots on the surface that come from high-heat baking. The caramelization creates a contrast between the slightly bitter, crackling top and the sweet, creamy custard beneath. It is essentially a crème brûlée effect applied to a handheld pastry.

Eileen Stow described the moment of breakthrough as a classic “light bulb moment.” Andrew had been tinkering for weeks, maybe months. Then one batch came out of the oven and everything clicked. The pastry was right. The custard was right. The top was right. He had created something that was neither fully Portuguese nor fully English but was recognizably, unmistakably its own thing.

His pharmaceutical background was not incidental to this process. Pharmacists are trained to isolate variables, adjust one element at a time, and document the results. Stow approached baking the way he had approached formulating medications: systematically, patiently, with an eye toward consistency and reproducibility. This is why Lord Stow’s tarts taste the same on the 14,000th tart of the day as they do on the first. The recipe was engineered for consistency, not just for flavor.

Lord Stow’s Bakery: From Coloane Workshop to Global Icon

Lord Stow’s Bakery officially opened its doors on September 15, 1989, in Coloane Village. Coloane is the southern island of Macau, a quieter, sleepier place than the bustling Macau Peninsula or the neon-drenched Cotai Strip. In 1989, Coloane was a fishing village with a laid-back, almost Mediterranean atmosphere. It was the kind of place where you could sit by the harbor and forget you were in China.

The bakery was small. Andrew Stow had not initially intended to build a global brand. He simply wanted to create good food for Macau’s Portuguese community, people who missed the pastries of home. The egg tarts were one product among several, not even the original focus of the business.

But the tarts found an audience, and not the audience Stow expected. The initial reaction from the Portuguese community was lukewarm. Many felt the tarts were not authentic. They were too creamy, too different from the pastel de nata they remembered from Lisbon. The tarts had been changed, and change can feel like betrayal when it comes to beloved foods from home.

The local Chinese community was equally skeptical at first, but for a completely different reason. Those dark, caramelized spots on top of the tart looked concerning. Many Chinese customers assumed the black spots meant the pastry was burnt or spoiled. Some genuinely thought eating them would make them sick. Stow had to educate customers that the spots were intentional, a sign of proper caramelization rather than a defect.

This initial rejection is worth pausing on. It reveals something important about how new food traditions are born. The Macau egg tart did not succeed because it was familiar. It succeeded because it was different enough to stand out, but good enough to win people over once they tried it. The black spots that initially frightened Chinese customers became the very thing that made Lord Stow’s tarts visually iconic. What was once a barrier to entry became a signature feature.

So who actually made Lord Stow’s famous? The answer, according to multiple accounts, is Hong Kong visitors. Hong Kong is just an hour away from Macau by ferry, and in the late 1980s and early 1990s, day-tripping Hong Kong residents discovered Lord Stow’s tarts and fell in love with them. They brought them back to Hong Kong as souvenirs. They told their friends. Food writers picked up the story. The “Macau Portuguese egg tart” became a must-try item for any Hong Kong visitor to Macau.

From there, word spread to Taiwan, mainland China, and eventually the broader world. Lord Stow’s Bakery expanded beyond Coloane to locations at The Venetian Macao resort and a production factory near Macau International Airport. The bakery now produces approximately 13,000 to 14,000 tarts per day across all locations, and the Coloane Village original still draws long queues of visitors who treat it as a pilgrimage site.

For travelers wondering which bakery to visit, the Coloane Village original remains the destination for the authentic experience. Many Reddit users describe it as a “pilgrimage” and note that the tarts taste significantly better when purchased fresh and warm directly from the bakery. The Venetian location is more convenient for tourists staying on Cotai, though some forum users note slight inconsistencies in quality between locations.

Macau vs Hong Kong vs Portuguese Egg Tarts: What Is the Difference

This is one of the most common questions people ask about egg tarts, and the confusion is understandable because all three traditions share a family resemblance. But they are distinct pastries with different histories, different techniques, and different eating experiences. Let me break down the differences clearly.

The Pastry Shell

Macau egg tarts use a flaky, layered puff pastry shell inspired by the Portuguese tradition. The dough is folded and rolled multiple times with butter to create thin, distinct layers that shatter when you bite into them. This is the same technique used for croissants or pastel de nata, and it produces a shell that is simultaneously crisp and delicate.

Hong Kong egg tarts (called daan tat in Cantonese) typically use either a shortcrust pastry or a simpler puff pastry. The shortcrust version is more like a butter cookie in texture: crumbly, dense, and slightly sandy. Some Hong Kong bakeries use a puff pastry version, but it is generally less layered and less flaky than the Macau or Portuguese version.

Portuguese pastel de nata uses a puff pastry shell that is very similar to the Macau version, since Stow borrowed directly from this tradition. However, traditional Portuguese shells are hand-moulded using a specific pounding technique that creates a slightly different texture than machine-pressed alternatives.

The Custard Filling

This is where the Macau egg tart truly separates itself from both relatives. Macau tarts have a creamier, more flowing custard thanks to Andrew Stow’s removal of corn flour and his use of a higher cream ratio. The filling is smooth, rich, and almost liquid when warm. It has a distinctly creamy character that reflects the English custard tart influence.

Hong Kong egg tarts have a stronger, more direct egg flavor. The custard is firmer and more set, often with a slightly gelatinous quality. It tastes more of eggs and less of cream. Many people who grew up eating Hong Kong tarts prefer this more assertive egginess over the creamier Macau version.

Portuguese pastel de nata uses corn flour to thicken the custard, which gives it a slightly jelly-like consistency that falls between the firm Hong Kong version and the creamy Macau version. The flavor is deeply caramelized with a slight lemon or cinnamon note depending on the bakery.

The Topping

Macau egg tarts have that signature caramelized, blistered top. The dark spots are created during high-temperature baking, when the sugar in the custard caramelizes on the surface. This creates a thin, crackly layer reminiscent of crème brûlée that contrasts with the creamy custard underneath.

Hong Kong egg tarts do not have a caramelized top. The surface is smooth and uniformly golden yellow. There is no crackly layer, no dark spots, no contrast between the top and the filling.

Portuguese pastel de nata does have a caramelized top, very similar to the Macau version. In fact, this is the element Stow borrowed most directly from the Portuguese tradition.

The Shape and Size

Macau egg tarts are typically slightly larger than Hong Kong tarts, with a wider, shallower shape that shows off the caramelized top. Hong Kong tarts are often more compact, with a deeper, more cup-like shape and a smooth, gently domed surface. Portuguese tarts are similar in size to Macau tarts but can vary more widely between bakeries.

In summary: if you want a creamy, flaky, caramelized tart, go for the Macau version. If you want a firm, eggy, simpler tart, go for the Hong Kong version. If you want the original monk-created classic with a jelly-like consistency and centuries of history, go for the Portuguese version.

The Chinese Egg Tart: Another Branch of the Family Tree

Before moving on, it is worth noting that the Hong Kong egg tart has its own origin story that is separate from both the Portuguese tradition and Andrew Stow’s creation. The Chinese egg tart emerged in the 1920s in Guangzhou (Canton), where department stores competed for customers by offering new, Western-inspired pastries at their in-store cafes.

These early Chinese egg tarts were inspired by English custard tarts, brought to southern China through Hong Kong’s British colonial connection. The department stores adapted the English recipe using local ingredients and techniques, creating the shortcrust-shelled, firm-custard daan tat that became a staple of Hong Kong’s cha chaan tengs (casual diners) after World War II.

The department store origin is an important detail. In 1920s Guangzhou, the major department stores like Wing On and Sincere competed fiercely for customers. Each store had its own restaurant or cafe, and offering exclusive Western-style pastries was a way to attract affluent, cosmopolitan shoppers. The egg tart was born as a competitive product, an adaptation of English custard tarts tailored to Chinese tastes with a firmer texture and stronger egg flavor.

When these department store egg tarts migrated to Hong Kong after World War II, they found a permanent home in the city’s cha chaan tengs. These bustling, casual diners served a mix of Western and Chinese dishes at affordable prices, and the egg tart became one of their signature items. By the time Andrew Stow arrived in Macau in 1979, the Hong Kong egg tart was a well-established cultural institution with decades of history.

So by the time Andrew Stow opened Lord Stow’s Bakery in 1989, Hong Kong already had its own well-established egg tart tradition. What Stow did was introduce the Portuguese element to Macau, creating a third branch of the egg tart family tree that was distinct from both the English-derived Hong Kong version and the Portuguese pastel de nata.

The fact that Macau, a Portuguese territory, did not already have a strong pastel de nata tradition before 1989 surprises many people. But Macau’s Portuguese community was relatively small and focused on other culinary traditions. It took an English pharmacist to recognize the gap, fill it, and turn it into a global phenomenon.

Visiting Lord Stow’s Bakery Today

If you are planning to visit Macau and want to taste the original Macau egg tart for yourself, Lord Stow’s Bakery is the destination. The original location is still in Coloane Village, at 1 Rua da Silva Mendonça, just a short walk from the Coloane ferry pier and the sleepy village square where Stow first opened shop in 1989.

The Coloane location has been expanded and renovated over the years, but it retains the character of a village bakery rather than a corporate chain. There is indoor and outdoor seating, and on weekends and holidays, the queue can stretch out the door and around the corner. Local advice: visit on a weekday morning if possible, and always eat the tarts warm.

Reddit users who have made the trip describe it in almost reverential terms. The experience of biting into a fresh Lord Stow’s tart, with its shatteringly crisp shell giving way to warm, flowing custard under a crackle of caramelized sugar, is frequently described as “unbelievable” and “worth the trip alone.” One user on r/food wrote about the “smooth and silky” custard and the pastry being unlike anything they had tried elsewhere. Another described the Coloane bakery as a “pilgrimage destination” that every food lover should experience at least once.

Temperature matters enormously. Forum users consistently note that Macau egg tarts are at their absolute best when eaten within minutes of coming out of the oven. The contrast between the warm, flowing custard and the crisp, cool pastry shell is what makes the experience special. Once the tart cools to room temperature, the custard firms up and the shell softens, and while it is still a good tart, it is not the same experience.

The bakery has expanded well beyond Coloane. There are now Lord Stow’s locations at The Venetian Macao, at the Macau Ferry Terminal, and at various other spots around the city. The production factory near Macau International Airport supplies the massive daily volume that keeps all locations stocked. According to reports, the bakery produces between 13,000 and 14,000 tarts per day, a staggering number for what started as a one-man operation in a village workshop.

Some forum users have noted occasional inconsistency between locations, with the Coloane original generally considered the gold standard. The factory-produced tarts at satellite locations are still very good, but the experience of eating a tart at the source, still warm from the oven in the village where it was born, is something that cannot be replicated elsewhere.

If you cannot make it to Macau, Lord Stow’s has also expanded internationally with locations in Japan, the Philippines, and other parts of Asia. These are franchise operations and the quality can vary, but they give people around the world a chance to taste the pharmacist’s creation without flying to southern China.

Andrew Stow’s Legacy and the Future of the Macau Egg Tart

Andrew Stow did not live to see the full global impact of his creation. He passed away in October 2006 at the age of 55, but not before receiving one of Macau’s highest honors. In January 2006, the Macau SAR government awarded Stow the Medal of Tourism Merit, recognizing his contribution to Macau’s cultural and culinary identity. The medal was a formal acknowledgment that an English pharmacist had created something that had become definitively, unmistakably Macanese.

The Medal of Tourism Merit is not given lightly. It is reserved for individuals who have made exceptional contributions to Macau’s tourism industry and cultural heritage. That the government chose to honor a British-born pharmacist with this award speaks volumes about how deeply the Macau egg tart had become embedded in the city’s identity by 2006. Andrew Stow was not just a successful businessman. He was recognized as someone who had helped define what Macau means to the world.

Stow’s funeral, as described in the BBC’s reporting, brought people from all walks of life: Portuguese expatriates, Chinese locals, Hong Kong day-trippers, chefs, government officials, and ordinary people who had simply loved his tarts. It was a testament to how a small bakery in a fishing village had become woven into the fabric of an entire community.

After Andrew’s death, his sister Eileen Stow took over the business. Eileen had been involved from the early days and understood both the recipe and the philosophy behind it. Under her leadership, Lord Stow’s Bakery continued to grow while maintaining the quality standards that Andrew had established. The family-run character of the business has been an important part of its identity and its appeal.

The Macau egg tart has also spawned a broader tart culture across the city. While Lord Stow’s is the original and most famous, other bakeries in Macau now produce their own versions. Some are excellent. Margaret’s Café e Nata, founded by Andrew Stow’s ex-wife Margaret Wong, is a notable alternative that some locals actually prefer. Cafe Litoral and other Taipa and Coloane establishments also offer their own takes on the Portuguese egg tart.

For visitors wondering whether Lord Stow’s is still “the best,” the honest answer is that it is the original and the most iconic, but Macau’s egg tart scene has matured. Part of the fun is doing a tart crawl, trying Lord Stow’s, Margaret’s, and other bakeries to taste the differences for yourself. Each has its own character, its own slightly different custard consistency, and its own loyal following.

The Macau egg tart’s cultural significance goes beyond taste. It has become a symbol of Macau itself, a city that exists at the intersection of Portuguese and Chinese worlds. That an English pharmacist created this symbol makes it even more fitting. Macau has always been a place where outsiders arrive, encounter the existing culture, and create something new by blending what they find with what they bring. Andrew Stow was simply the most delicious example of this pattern.

On forums and in travel writing, people sometimes ask whether the “British pharmacist” story is real or just a marketing myth. The answer, confirmed by BBC reporting, SCMP investigations, Eileen Stow’s first-hand accounts, and the documented history of Anglo French Laboratories in Macau, is that the story is absolutely real. Andrew Stow was a genuine industrial pharmacist who genuinely transitioned from pharmaceuticals to baking and genuinely created a new pastry by combining two existing traditions with scientific precision.

This authenticity is part of what makes the Macau egg tart story so powerful. In an era of manufactured food origin stories and marketing-driven “authenticity,” the tale of a pharmacist from Essex who accidentally created Macau’s signature pastry through systematic experimentation is refreshingly, verifiably true. And as someone who has documented Macau’s cultural landscape in depth, I can confirm that this story resonates deeply with the people of Macau. They claim Andrew Stow as one of their own, regardless of where he was born.

FAQs

Why the Macau Egg Tart Was Invented by a British Pharmacist: A Story That Still Matters

The story of why the Macau egg tart was invented by a British pharmacist is more than a quirky food trivia fact. It is a story about how cultural fusion actually works in practice. Not through grand plans or marketing strategies, but through individual people who encounter something new, fall in love with it, and cannot resist trying to make it their own.

Andrew Stow did not set out to create Macau’s signature pastry. He set out to make good food for a community he cared about, using skills from a completely different profession. His pharmaceutical precision became his baking advantage. His English palate became his creative direction. His willingness to fail, experiment, and try again became the engine that produced one of the world’s most beloved pastries.

If you ever find yourself in Coloane Village, standing in the queue outside Lord Stow’s Bakery, take a moment to appreciate what you are about to eat. That tart in your hand is the product of 13th-century Portuguese monks, medieval English bakers, an Austrian hotel chef, and one fearless pharmacist from Essex who believed he could make something better. He was right, and Macau has been thanking him ever since.
