A Brief History of Xiao Long Bao: Shanghai’s Signature Dish
Discover the fascinating story behind Shanghai’s beloved xiao long bao, a dumpling renowned for its delicate skin, savory filling, and rich soup.

Among the treasures of Chinese cuisine, xiao long bao—those delicate steamed soup dumplings—stand out as a culinary icon. From modest beginnings in the towns surrounding Shanghai to celebrated menus in cities across the globe, xiao long bao’s story is woven from history, legend, and ingenious culinary artistry. This article delves into the origins, evolution, and modern-day prominence of Shanghai’s most cherished dumpling.
Introduction: What is Xiao Long Bao?
Xiao long bao (小笼包), translated literally as “small basket bun,” are a special kind of steamed dumpling commonly associated with Shanghai and the Jiangnan region. These morsels feature an impossibly thin wheat flour wrapper enveloping a savory filling—traditionally pork—alongside gelatinized broth (aspic) that melts into soup when steamed. Traditionally, they’re served in bamboo baskets and consumed fresh from the steamer, offering a burst of aromatic soup with every careful bite.
- Main ingredients: wheat flour, pork, aspic (meat gelatin), sometimes crab roe or other fillings
- Cooking method: steamed in bamboo baskets
- Key characteristic: skin is thin yet strong; dumpling bursts with soup inside
- Typical serving style: several pieces per bamboo steamer basket, accompanied by black vinegar and ginger slivers
The Origins of Xiao Long Bao
The Nanxiang Legend: Huang Mingxian’s Delight
The most widely accepted historical account credits Huang Mingxian, proprietor of the Ri Hua Xuan restaurant in Nanxiang, a small town near Shanghai, with inventing xiao long bao in the 1870s. At a time when steamed buns (mantou) dominated local food stalls, Huang’s distinctive innovation involved wrapping minced pork mixed with aspic into a small, pleated dumpling. Upon steaming, the aspic would melt, turning into a delightful soup enclosed within the dumpling skin. This ingenious method rapidly attracted diners from across the area.
- The dish was first named Nanxiang da rou mantou (“Nanxiang large meat bun”), though its actual size was petite, amplifying its surprise effect on first-time diners.
- Customers began referring to them as Nanxiang xiao long bao—“small basket buns from Nanxiang.”
- Popularity soared quickly, marking the dawn of a Shanghai staple.
Emperor Qianlong and the Jiangsu Tale
A competing legend traces the dish’s fame back to Emperor Qianlong (1711–1799), who reputedly encountered these soup-filled dumplings while journeying through Wuxi, in Jiangsu province. Enthralled by their flavor, the Emperor’s endorsement supposedly made them famous throughout the region. Some stories play with the homonym “long,” suggesting that “dragon” could be the meaning in “xiao long bao,” in his honor—a playful debate given that “long” (笼) in the dish’s name actually means “basket.”
Older Roots: The Kaifeng Connection
Some food historians suggest that xiao long bao evolved from guantangbao, soup-filled buns of Kaifeng—the capital city during the Northern Song Dynasty (960–1127). While the methods and exact form differ, the principle of encasing savory soup and meat fillings within a flour wrapping is ancient, with each region developing its own variation.
From Neighborhood Specialty to National Icon
Initially a local phenomenon of Nanxiang, xiao long bao’s fame gradually spread beyond the region thanks to urban migration, word of mouth, and the rising prominence of Shanghai as an economic center in the late 19th and early 20th centuries:
- Street-side stalls and small tea houses served them fresh from steaming baskets to working-class diners and travelers alike.
- By the early 20th century, they were firmly established as a Shanghai must-try specialty, served at grand banquets and humble eateries alike.
Craftsmanship: The Art of Pleating
A hallmark of authentic xiao long bao is the pleating at the top: the best are said to have precisely 14 outward pleats, each hand-pinched to create a tight enclosure for the filling and soup. This delicate artistry is a rite of passage for skilled dim sum chefs.
- The skin is delicate but must be strong enough not to rupture during steaming.
- Mastering the pleating technique ensures an eye-catching presentation and helps keep the soup securely sealed inside.
- Soup is created from slow-cooked gelatinized pork broth that liquefies during steaming for that signature burst of flavor.
Xiao Long Bao Beyond Shanghai
From the mid-1900s, waves of migration—particularly those following the Chinese Civil War—spread Shanghai’s food culture, including xiao long bao, to other corners of China and beyond.
- Taiwan: In the late 1940s, restaurateurs brought Shanghai-style soup dumplings to Taipei. Din Tai Fung, established in 1972, later became globally famous for its xiao long bao.
- Global Chinese cuisine: As Chinese communities formed in North America, Southeast Asia, Australia, and Europe, soup dumplings gained a foothold in Chinatown restaurants and beyond.
- Today, xiao long bao is both a marker of Shanghai identity and a dish enjoyed on five continents.
Regional Styles and Fillings
Though pork remains the classic filling, variations exist reflecting local tastes and creativity:
- Pork and crab roe (蟹粉小笼包): A highly prized seasonal variant in Shanghai and Yangzhou, featuring a richer, brinier filling.
- Chicken, shrimp, and vegetarian: Filling innovations abound, including versions with mushrooms, seafood, and even abalone in high-end restaurants.
- Wrappers: Some variants use slightly thicker or thinner dough, impacting the eating experience.
How to Eat Xiao Long Bao Properly
Appreciating xiao long bao involves both savoring its flavor and navigating the hot, soupy interior without mishap. Here’s the traditional approach:
- Carefully pick up the dumpling from the bamboo basket with chopsticks, cradling its body to avoid puncturing the skin.
- Place the bun onto a spoon, often with slivers of pickled ginger and a dash of black vinegar.
- Bite a small hole at the top or side to release and slurp some hot soup.
- Enjoy the dumpling in one or two mouthfuls, savoring the filling and rich broth together.
Tip: Let the dumpling cool slightly before eating to avoid burning your mouth!
Secrets Behind the Soup: Culinary Science
The magic of xiao long bao centers on the creation of “soup” inside the dumpling. The process uses aspic—a gelatin made by cooking pork skin, bones, or other collagen-rich cuts for hours, resulting in a concentrated broth that solidifies when cooled. When mixed in with the minced meat and sealed into the wrapper, the aspic melts into a savory soup as the dumplings steam.
| Component | Purpose | Significance |
|---|---|---|
| Wheat flour dough | Creates thin but resilient wrapper | Delicate yet strong enough to contain hot soup |
| Pork aspic (gelatin) | Melts during steaming to become soup | Provides signature burst of hot broth |
| Minced pork | Main flavor of the filling | Rich, savory, and tender texture |
| Pleating technique | Seals dumpling, creates iconic look | Keeps soup inside; signals authentic craftsmanship |

What was once a humble snack is now a “must-try” feature of global Asian cuisine.
