Authentic Cantonese Siu Mai (Pork & Shrimp Dumplings)

Few dishes capture the heart of Cantonese dim sum like Siu Mai — the open-topped dumpling filled with tender pork, springy shrimp, and savory aromatics. This recipe simplifies the classic process into clear, manageable steps while preserving its authentic flavor and texture. The secret lies in the mixing technique and the freshness of the ingredients.

 Overview

Yield: 30–35 dumplings
Prep Time: 45 minutes
Cook Time: 10–12 minutes per batch

Ingredients

For the Filling:

• 250g (½ lb) ground pork (preferably from pork shoulder, with some fat)
• 150g (5 oz) raw shrimp, peeled, deveined, and roughly chopped
• 100g (3.5 oz) fresh shiitake mushrooms, finely diced (or rehydrated dried ones)
• ¼ cup (50g) finely minced bamboo shoots (optional, adds crunch)
• 2 tablespoons finely minced scallions (green parts only)
• 1 tablespoon finely minced ginger

Seasonings:

• 2 tablespoons light soy sauce
• 1 tablespoon oyster sauce
• 2 teaspoons Shaoxing rice wine
• 1 teaspoon sesame oil
• ½ teaspoon white pepper
• ½ teaspoon sugar
• 1 teaspoon cornstarch

For Juiciness (The Secret):

• 3–4 tablespoons iced water or cold chicken stock

Additional:

• 1 package round yellow siu mai wrappers (30–35 pieces)
  (Thicker than wonton wrappers; if unavailable, thin wonton wrappers can substitute)
• Optional garnish: carrots, goji berries or green peas

For Steaming:

• Parchment paper or cabbage leaves (to line steamer)

Equipment:

• Bamboo or metal steamer
• Large mixing bowl

 Step 1: Prepare and Mix the Filling

Velvet the Shrimp (秘技):
In a small bowl, toss the chopped shrimp with ¼ teaspoon baking soda. Let rest for 10 minutes, then rinse under cold water and pat dry. This “velveting” step ensures the shrimp turns springy and tender.

Combine the Proteins:
In a large bowl, add the ground pork and shrimp. Stir vigorously in one direction only for 2–3 minutes until the mixture turns sticky and paste-like.

Add Seasonings:
Mix in soy sauce, oyster sauce, Shaoxing wine, sesame oil, white pepper, sugar, and cornstarch. Continue stirring in the same direction for another minute.

Water-Stirring Technique (打水 Dǎ Shuǐ):
While mixing, add iced water or stock one tablespoon at a time, allowing each to be fully absorbed before adding more. The mixture will become glossy and airy — this is the key to juicy Siu Mai.

Add Vegetables:
Fold in mushrooms, bamboo shoots, scallions, and ginger. Mix gently to combine — avoid over-mixing to preserve texture.

Chill:
Cover and refrigerate the filling for at least 30 minutes before wrapping.

 Step 2: Wrap the Siu Mai

1. Prepare the Wrapper: Place one round wrapper in your palm.
2. Add Filling: Spoon about 1 tablespoon of filling into the center.
3. Shape: Gather the edges upward and gently squeeze around the middle so the top remains open.
4. Flatten Base: Tap the bottom lightly so the dumpling can stand upright.
5. Garnish: Place carrot pieces, goji berry, or a green pea on top for the classic look.
6. Keep Moist: Cover finished Siu Mai with a damp cloth while working on the rest.

 Step 3: Steam the Siu Mai

1. Prepare Steamer: Fill wok or pot with water, ensuring it doesn’t touch the steamer bottom. Bring to a rolling boil.
2. Line the Basket: Use parchment with holes or cabbage leaves to prevent sticking.
3. Arrange: Place dumplings about ½ inch apart.
4. Steam: Cover and steam on high heat for 8–10 minutes until fully cooked and translucent.

🍶 Step 4: Serve and Enjoy

Serve hot, straight from the steamer.

Classic Dipping Sauce:
Mix Chinese red vinegar (浙醋) with thinly sliced ginger.
Alternatively, combine soy sauce and chili oil for a spicier edge.

Pro Tips for Perfect Siu Mai

• Mix in one direction: Aligns protein strands for a springy, cohesive bite.
• Avoid over-mixing after adding vegetables to preserve texture.
• Keep wrappers moist: Cover unused ones with a damp cloth.
• Taste-test first: Cook a spoonful of filling to adjust seasoning before wrapping all.

A plate of freshly steamed Siu Mai captures the soul of Cantonese cuisine — delicate, savory, and comforting. Enjoy them slowly, as they do in Hong Kong’s morning tea houses.
