On Chinese dining tables, buns (baozi) and dumplings (jiaozi) are like twins with very different personalities. They share a similar “genetic code”—both are dough wrapped around fillings—and sometimes even use the same mixture of pork and cabbage prepared by the cook.
Yet when they are served steaming hot, the difference becomes obvious. Buns feel gentle and mellow, carrying the aroma of fermented wheat and often juicy fillings. Dumplings, on the other hand, feel more crisp and direct, with thin elastic skins that deliver flavor straight to the palate.
So why is this the case?
1. The difference in dough
The first major dividing line between buns and dumplings lies in whether the dough is “alive” or not—whether it has undergone fermentation.
Buns use yeast-fermented dough. This gives the dough airiness, softness, and a slightly sweet wheat aroma. During steaming, the trapped gas expands, creating a fluffy texture that absorbs juices from the filling, resulting in a tender and moist bite.

Dumpling dough, by contrast, is typically unleavened. It is made with water and flour alone, kneaded into a firm, elastic texture. Because it does not expand, it stays thin and slightly chewy after boiling, allowing the filling’s flavor to stand out more directly.
In simple terms: buns are about softness and integration, while dumplings are about precision and clarity of taste.
Bun wrappers are made from fermented dough. Yeast produces countless tiny air pockets inside the dough, like microscopic “reservoirs.” During steaming, these pores continuously absorb the oil and juices released from the filling.
Because of this, the most delightful part of eating a bun is often the outer layer of dough that has been soaked through with meat juices—neither fully dry nor fully wet. It becomes a soft fusion of wheat aroma and savory filling, where the flavors of dough and meat are deeply integrated.
Dumpling wrappers, in contrast, pursue a kind of “lean precision.” They are not fermented, and instead emphasize thinness, elasticity, and chewiness. The wrapper acts like a tight-fitting lacquered dance costume, holding the filling firmly in place. When you bite into it, the juices burst out directly, delivering a fresher and more immediate flavor—bright, sharp, and satisfying in a way that feels like a tactile “collision” between teeth and dough.
2. Differences in cooking methods
The cooking method also plays a decisive role in shaping their final textures and flavors.
1. Buns are steamed
Steaming is a relatively gentle cooking process. Inside a sealed steamer, buns are like they are taking a sauna bath. Warm steam slowly penetrates the dough, while the filling inside undergoes a slow cooking process, almost like braising.
Over time—usually more than 15 minutes—the meat and vegetables fully blend together, forming a rich, layered, and harmonious flavor profile.
2. Dumplings are ‘boiled’
Boiling water is an intense form of heat transfer. Once dumplings are dropped into the pot, they tumble rapidly in high-temperature water. Within just a few minutes, the filling is quickly cooked through.
This fast cooking process helps preserve the crisp texture of vegetables and the tender juiciness of the meat. As a result, what dumplings emphasize most is that burst of “freshness”—a clean, immediate, and lively flavor.
3. Differences in seasoning
Although the fillings can be similar, seasoned food lovers will notice that the logic of seasoning is quite different between buns and dumplings.
To complement the aroma of fermented dough, bun fillings often include a slightly higher amount of cooking wine to remove any unwanted odor, and sometimes a touch of sugar to enhance overall umami and create a smoother flavor profile.
Dumplings, on the other hand, need to withstand flavor loss during boiling. Therefore, they are usually seasoned more “boldly.” Soy sauce and minced ginger tend to play a more prominent role, ensuring that even after cooking, the dumplings remain savory and well-seasoned.
4. Differences in shaping
Buns are typically fully sealed. They are like small pressure cookers, locking all the aromas tightly within their pleats. Only when you take a bite does the accumulated fragrance suddenly release.
Dumplings, however, have pleated edges that are thicker and more textured. During boiling, a subtle exchange occurs between the wrapper and the water, giving dumpling juices a lighter, fresher character—less dense and less greasy than buns.
5. Differences in how they are eaten
Beyond physical differences, our emotional connection to them is also distinct.
Buns are often associated with “mornings.” On a busy street, holding a warm, soft bun feels like a gentle start to the day.
Dumplings, however, are more often tied to festivals, family gatherings, and full meals. When everyone sits together around the table, dipping dumplings into vinegar and garlic, the experience carries a sense of celebration and warmth—something deeply rooted in shared life and together.
6. Home cooking tips
1. Want buns to be more irresistible?
When mixing the filling, add a little stock jelly (or a small amount of water). After steaming, this will create a delightful “juicy burst” effect inside the bun—rich, moist, and highly appetizing.
2. Want dumplings to be more springy?
When kneading the dough, add one egg or a small spoon of salt. After letting the dough rest for about 20 minutes, roll out the wrappers. This will significantly improve elasticity, giving your dumpling skin a pleasantly chewy, “alive” texture.
3. A simple finishing touch
For both buns and dumplings, lightly brushing a bit of sesame oil right after cooking makes a noticeable difference. It enhances the visual appeal with a glossy sheen and immediately elevates the aroma, making the entire dish feel more refined and complete.
