What Is Siu Mai?
Siu Mai (also spelled shao mai, shuumai, or shumai) is a type of open-faced Chinese steamed dumpling, typically filled with a combination of pork and shrimp, and topped with colorful garnishes. Its signature shape—upright with ruffled edges and exposed filling—is iconic, making siu mai an essential offering at Cantonese dim sum.
While regional variations exist across China and Southeast Asia, the classic Cantonese siu mai centers on fatty pork and tender shrimp, occasionally combined with mushrooms or bamboo shoots for texture. The wrappers are usually thin sheets of wheat dough, sometimes with added egg for elasticity and color.
The Story of Siu Mai: History & Regional Variations
Siu Mai originated in China, with the earliest records pointing to the Mongol Yuan dynasty (1271–1368). The dish became a staple of southern Chinese—particularly Cantonese—cuisine, eventually spreading to Hong Kong and around the world.
- Cantonese Siu Mai: Pork and shrimp, sometimes mushrooms, wrapped in egg-based wheat skins, garnished with fish roe or vegetables.
- Sichuan Siu Mai: Often features glutinous rice in the filling, spiced differently.
- Japanese Shumai: Usually smaller, filled with ground pork, sometimes topped with a green pea.
- Southeast Asian Variations: Sometimes add crab meat or other seafood.
The rapid rise of dim sum culture in southern China and Hong Kong made siu mai a centerpiece for tea houses and celebratory meals, symbolizing festivity and abundance.
Essential Ingredients for Classic Siu Mai
The flavor and texture of siu mai rely upon a few key components:
- Pork: Use fatty ground pork, ideally with at least 20% fat content, for the signature tender texture and juiciness.
- Shrimp: Fresh or frozen raw shrimp, peeled and deveined, add sweetness and bouncy texture.
- Wonton Wrappers: Square or round thin wheat skins; yellow ones typically contain egg.
- Soy Sauce: For seasoning; light soy sauce is preferred.
- Shaoxing Wine: A Chinese rice wine that adds depth and complexity.
- Sugar and Salt: Essential for balancing flavors.
- Aromatics: White part of green onions and sometimes ginger.
- Mushrooms (optional): Dried shiitake mushrooms, rehydrated and finely chopped, contribute umami and texture.
- Garnish: Flying fish roe, carrot, or green pea for a pop of color.

2. Mixing the Filling
In a large bowl, combine the following ingredients:
- 350g (about 13oz) fatty ground pork
- 150g (about 5oz) raw, chopped shrimp
- 3 (rehydrated) dried shiitake mushrooms, chopped

Mix vigorously with your hands or a sturdy spoon until the mixture becomes sticky and pasty, creating structure for the dumplings.
3. Wrapping the Dumplings
- Form an “O” shape with your thumb and forefinger, creating a ring to hold the wrapper.
- Place a wonton wrapper over the “O,” gently push a heaped teaspoon of filling into the center, using your finger or a butter knife to press and level the meat to the top.
- Gather up the edges so the wrapper stands upright around the filling, leaving the top open.
- If using square wrappers, fold down any excess corners or “flappy bits” with a dab of water to maintain a tidy shape; round wrappers skip this step.
- Flatten the base gently on your work surface, making sure the dumpling stands tall and open-faced.
4. Steaming the Siu Mai
- Line a bamboo steamer (or metal steamer) with parchment paper punched or cut with holes for steam circulation.
- Arrange dumplings snugly but not touching, about 20–25 per 12″ steamer basket.
- Fill a wok or pan with a few cups of water, bring to a rapid simmer (not boil).
- Place the steamer over the simmering water, cover, and steam for around 8 minutes, until the filling reaches 75°C / 165°F internally.
- Remove steamer and lid, garnish each dumpling with fish roe, pea, or carrot as desired.
5. Serving and Dipping Sauces
Siu Mai is best served hot, directly from the steamer. Traditional dipping sauces include:
- Soy Sauce
- Chinese Black Vinegar or white rice vinegar
- Chili Paste: Sriracha or Chinese chili oil
Many enjoy customizing the dipping sauce; a classic ratio is 3 parts soy sauce, 1 part vinegar, and a dash of chili, mixed to personal taste.
Expert Tips for Success
- Fat Content Matters: Choose pork with at least 20% fat for a juicy, succulent filling. Meat that’s too lean will result in dry dumplings.
- Mixing Method: Vigorously stir or knead the filling so it develops a sticky, pasty texture—this is essential for binding and juiciness.
- Wrapper Choice: Egg-based wonton wrappers hold their shape and add a gentle richness. Both round and square wrappers work, but adjust folding technique as needed.
- Don’t Overstuff: Overfilling wrappers can make steaming uneven; aim for heaping teaspoon per dumpling.
- Steamer Setup: Bamboo steamers add a subtle fragrance to the finished dumplings, but metal steamers work with proper lining.
- Serve Immediately: Siu Mai loses quality as it cools; offer right out of the steamer for best taste and texture.
Common Variations and Substitutions
