The Origins of Char Siu Bao (Bánh Bao Xá Xíu)

The history of Bánh Bao Xá Xíu is deeply rooted in Chinese culinary traditions, particularly in Cantonese cuisine. The dish is thought to have originated in Guangdong, China, where Char Siu, the barbecue pork, is a traditional delicacy. Char Siu, which literally means “fork roast,” is a type of barbecued pork that is marinated in a savory-sweet sauce, often made with hoisin sauce, soy sauce, five-spice powder, and honey. The pork is then roasted until it is beautifully caramelized on the outside and tender on the inside.

Char Siu Bao was created as a way to enjoy this flavorful roasted pork in a portable, bite-sized format. The fluffy steamed buns encase the tender, sweet pork filling, making it a convenient and satisfying snack. Over time, Char Siu Bao became popular in dim sum restaurants, where it is often served as part of a larger spread of small dishes.

The Vietnamese version, Bánh Bao Xá Xíu, has its roots in the influence of Cantonese cooking on Vietnamese cuisine, particularly in the southern regions, where Chinese immigrants have had a significant impact. Bánh Bao Xá Xíu is served in both casual eateries and high-end restaurants in Vietnam, reflecting its broad appeal across different cultures.

The Key Ingredients in Char Siu Bao (Bánh Bao Xá Xíu)

Char Siu Bao consists of two main components: the fluffy dough and the savory Char Siu filling. Let’s take a closer look at the ingredients that make this dish so irresistible.

1. Char Siu (Cantonese Barbecued Pork)

The heart and soul of Bánh Bao Xá Xíu is the filling—Char Siu—which is made from tender pork (usually pork shoulder or pork belly). The pork is marinated in a sauce made from:

• Hoisin sauce: This thick, dark sauce made from fermented soybeans provides a rich, sweet umami flavor to the pork.
• Soy sauce: Adds saltiness and depth to the marinade.
• Five-spice powder: A traditional Chinese spice blend that includes star anise, cloves, Chinese cinnamon, Sichuan peppercorns, and fennel seeds. It adds complexity and warmth to the dish.
• Honey or malt sugar: Used to create a shiny, caramelized glaze when the pork is roasted or grilled.
• Garlic and ginger: These aromatic ingredients contribute pungency and freshness to the pork marinade.

Once marinated, the pork is roasted or grilled until it develops a rich, caramelized exterior and a juicy, tender interior. The pork is then chopped into small pieces to fill the bao buns.

2. Bao Dough

The dough for Char Siu Bao is what gives the buns their soft, pillowy texture. The key ingredients for bao dough include:

• Flour: The base of the dough, which is typically all-purpose flour.
• Yeast: Essential for making the dough rise and become light and airy.
• Sugar: Adds a hint of sweetness to balance the savory filling.
• Baking powder: Helps to create the soft, fluffy texture.
• Milk or water: Liquid used to hydrate the dough and activate the yeast.
• Vegetable oil: Helps to keep the dough soft and tender.

The dough is kneaded and allowed to rise before it is portioned into small rounds, which are then filled with the Char Siu pork and steamed to perfection.

3. Other Ingredients for Garnish and Flavor

In addition to the core ingredients, some versions of Bánh Bao Xá Xíu include:

• Green onions: These are sometimes added to the filling for a touch of freshness and color.
• Sesame oil: A small amount of sesame oil can be added to the filling for an extra layer of flavor.
• Rice vinegar: Used in some recipes to balance the sweetness of the filling.

How to Make Char Siu Bao (Bánh Bao Xá Xíu) at Home

Making Bánh Bao Xá Xíu from scratch might seem like a daunting task, but with the right ingredients and a bit of practice, you can create this delicious dish at home. Here’s a step-by-step guide to making these savory buns.

Ingredients:

• For the Char Siu filling:
  • 500g pork shoulder or pork belly
  • 3 tablespoons hoisin sauce
  • 2 tablespoons soy sauce
  • 1 tablespoon Chinese rice wine or sherry
  • 1 tablespoon honey
  • 1 tablespoon oyster sauce
  • 1 teaspoon five-spice powder
  • 1 clove garlic, minced
  • 1 tablespoon grated ginger
  • 1 tablespoon vegetable oil
• For the bao dough:
  • 2 cups all-purpose flour
  • 1 tablespoon sugar
  • 2 teaspoons baking powder
  • 1 teaspoon active dry yeast
  • 1/2 cup warm water or milk
  • 1 tablespoon vegetable oil
  • Pinch of salt

Instructions:

1. Prepare the Char Siu Pork:

• In a bowl, combine the hoisin sauce, soy sauce, rice wine, honey, oyster sauce, five-spice powder, garlic, ginger, and vegetable oil to create the marinade.
• Cut the pork into strips or small chunks, depending on your preference.
• Place the pork in the marinade and mix well. Let it marinate in the refrigerator for at least 2 hours or overnight for more flavor.
• After marinating, preheat your oven to 375°F (190°C) and roast the pork on a baking sheet for about 30 minutes or until it’s cooked through and slightly caramelized. Alternatively, you can grill the pork on a barbecue for a smokier flavor.
• Once cooked, let the pork cool before chopping it into small, bite-sized pieces. Set aside.

2. Make the Bao Dough:

• In a large mixing bowl, combine the flour, sugar, salt, and baking powder.
• In a separate bowl, mix the warm water or milk with the yeast and let it sit for 5 minutes to activate.
• Add the yeast mixture and vegetable oil to the dry ingredients and mix until a dough forms.
• Knead the dough on a floured surface for about 8–10 minutes until smooth and elastic.
• Place the dough in a lightly oiled bowl, cover with a damp cloth, and let it rise for 1–2 hours or until it has doubled in size.

3. Assemble the Bánh Bao Xá Xíu:

• Punch down the dough and divide it into small portions (about 12–14 pieces).
• Roll each piece of dough into a ball and flatten it into a circle about 4 inches in diameter.
• Place a spoonful of the Char Siu filling in the center of each dough circle.
• Carefully fold the edges of the dough over the filling and pinch them together to form a sealed bun.
• Place each bun on a piece of parchment paper and let them rise for another 30 minutes.

4. Steam the Bao:

• Bring a pot of water to a simmer in a steamer or a large pot with a steaming rack.
• Place the buns in the steamer basket, ensuring that they are not touching each other. Steam the buns for about 15–20 minutes, or until they are fully cooked and the dough is soft and fluffy.
• Remove from the steamer and let the buns cool slightly before serving.

Serving and Enjoying Bánh Bao Xá Xíu

Bánh Bao Xá Xíu is best enjoyed warm, straight from the steamer. The soft, fluffy buns paired with the savory, slightly sweet pork filling create a harmonious combination of flavors and textures.
