In the culinary heart of Shunde (顺德), a district in Guangdong Province often hailed as the birthplace of Cantonese cuisine, there is a dessert so iconic that it has been crowned the “King of Cantonese Desserts” . Its name is Shuang Pi Nai (双皮奶) – literally “Double-Skin Milk” – a silky, custard-like treat that has been captivating taste buds for over a century. With its delicate double-layered skin, rich dairy aroma, and melt-in-your-mouth texture, this humble dessert has become a beloved symbol of Shunde’s culinary heritage and a certified provincial intangible cultural heritage.
The Accidental Invention: A Story of Serendipity
Like many great culinary creations, Shuang Pi Nai was born from a happy accident. The most widely told story begins in the early 20th century in Daliang, Shunde. A farmer named Dong Xiaohua (董孝华) – affectionately known as “Cowboy Hua” – made a living raising water buffalo and selling their rich, creamy milk.
At the time, without refrigeration, preserving fresh milk was a constant challenge. One day, Dong tried boiling the milk to extend its shelf life. To his surprise, he noticed that as the boiled milk cooled, a thin, delicate skin formed on its surface. Intrigued, he tasted it and found it incredibly smooth, sweet, and fragrant. This was the “first skin.”
Driven by curiosity, Dong wondered if he could create a second skin. He carefully pierced the first layer, poured out the milk beneath, mixed it with egg whites and sugar, and poured it back into the bowl. After a second round of steaming, a new, even richer skin formed on top. He called his creation “Jia Pi Nai” (加皮奶 – “Added-Skin Milk”) before settling on the more poetic name “Shuang Pi Nai” (Double-Skin Milk).
From Family Kitchen to Culinary Empire
Dong Xiaohua’s accidental invention soon became a family legacy. In the early 1930s, he opened Minxin (民信), the first shop to sell his double-skin milk on Huagai Road in Daliang. In 1938, his daughter Dong Jiewen (董洁文) took the recipe and opened her own shop, Renxin (仁信), turning their family’s store into a dedicated dessert house.
The Dong family’s two brands – Minxin and Renxin – would go on to become the most famous names in Shuang Pi Nai, each carrying forward the same century-old tradition. Over the decades, the business weathered political upheavals, including nationalisation in 1958. But in 1979, at the age of 66, Dong Jiewen secured the very first individual business license issued in Daliang after the reform era, resurrecting the Renxin brand. Today, both brands operate multiple stores across Guangdong and beyond, preserving the taste that has defined Shunde for generations.
The Art of the Double Skin
So what makes Shuang Pi Nai so special? The secret lies in both the ingredients and the craft.
The foundation is water buffalo milk, which is far richer than ordinary cow’s milk. With a butterfat content of around 8% – more than double that of regular milk – it creates a thicker, more luxurious skin. This is combined with fresh egg whites and sugar.
The preparation is a meticulous, multi-step process that can take over three hours:
- Boil and skin: Fresh water buffalo milk is heated until just boiling, then quickly poured into small bowls. As it cools, the first creamy skin forms on the surface.
- Pierce and pour: A small hole is made in the first skin, and the milk beneath is carefully poured out, leaving the skin intact at the bottom of the bowl.
- Mix and return: The poured milk is mixed with egg whites and sugar, then strained and poured back through the hole in the first skin.
- Steam: The filled bowls are steamed gently until the mixture sets, forming a second, thicker skin on top.
The result is a dessert of sublime contrasts: the top skin is sweet and fragrant, while the bottom skin is smooth and creamy. The texture is silky, delicate, and almost pudding-like, with a rich, lingering dairy aroma that Shunde locals describe as the taste of home.
A Taste of Heritage and Innovation
In 2018, the Shuang Pi Nai making technique was officially inscribed on Guangdong Province’s Intangible Cultural Heritage list. It has also been recognised as a “China Famous Snack” and a “Guangdong Famous Snack”. Today, the dessert is a source of immense local pride – even Olympic medalists have declared it the dish they miss most.
While the classic original remains the gold standard, Shuang Pi Nai has evolved with the times. Modern variations include red bean, lotus seed, mango, durian, and even coffee flavours. Some shops serve it chilled or hot, while others have created new forms like coconut milk double-skin or bamboo-tube double-skin. It has even inspired modern interpretations like double-skin milk tea.
Where to Find the Real Deal
If you’re visiting Shunde, the place to start is Huagai Road Pedestrian Street (华盖路步行街) in Daliang, where both Minxin and Renxin have their historic shops. Renxin now operates stores in Guangzhou, Shenzhen, Zhuhai, and other cities. For a deep dive into the dessert’s history, visit the Minxin Double-Skin Milk Museum, which tells the story of the Dong family and their century-old creation.
A Sweet Legacy
Shuang Pi Nai is more than just a dessert – it is a taste of Shunde’s history, a testament to the ingenuity of a farmer who turned a happy accident into a culinary legacy, and a symbol of the region’s deep-rooted food culture. Whether you’re savouring it in a historic shop in Daliang or a modern café in Guangzhou, every spoonful carries the story of a family, a craft, and a century of sweet perfection. As the locals say: “A bowl of Shuang Pi Nai is a bowl of Shunde’s soul.”
