What are Char Siu Bao?

Char Siu Bao (叉燒包), literally translated as “barbecue pork bun,” are steamed buns filled with Char Siu, a Cantonese style of barbecued pork. The buns are typically white and fluffy, made from a yeast-raised dough. The filling is sweet, savory, and slightly sticky, complementing the soft texture of the bun. These buns are a popular snack, breakfast item, and dim sum dish, enjoyed by people of all ages.

Why Make Char Siu Bao at Home?

While you can easily find Char Siu Bao at many Chinese restaurants and bakeries, making them at home offers several advantages:

* **Freshness:** Homemade Char Siu Bao are undoubtedly fresher and more flavorful than store-bought versions.
* **Customization:** You can adjust the sweetness, saltiness, and spice levels of the filling to your preference.
* **Quality Ingredients:** You have control over the ingredients, ensuring you’re using high-quality pork and avoiding unnecessary additives.
* **Satisfaction:** There’s a unique sense of satisfaction that comes from making something from scratch, especially a dish as iconic as Char Siu Bao.
* **Dietary Control:** If you have dietary restrictions, such as gluten intolerance (with modifications) or want to reduce sodium or sugar, making them yourself is the best option.

Ingredients for Char Siu Bao

Let’s start by gathering the ingredients. We’ll divide them into two categories: the dough and the filling.

Dough Ingredients:

* **All-Purpose Flour:** 300g (approximately 2 1/2 cups), provides the structure of the bun.
* **Instant Yeast:** 1 tsp (3g), crucial for the dough to rise and create a fluffy texture.
* **Baking Powder:** 1 tsp (4g), adds extra lightness to the buns.
* **Sugar:** 60g (approximately 1/4 cup), provides sweetness and feeds the yeast.
* **Salt:** 1/2 tsp (3g), enhances the flavor and controls yeast activity.
* **Milk:** 150ml (approximately 2/3 cup), warm (around 110°F or 43°C), adds moisture and richness to the dough. Make sure the milk is not too hot, as it can kill the yeast.
* **Shortening or Lard:** 30g (approximately 2 tablespoons), contributes to the tenderness and flakiness of the bun. Vegetable shortening or lard work well.
* **Optional: Ammonium Bicarbonate:** 1/4 tsp (optional, but highly recommended for that classic bakery aroma and texture) – dissolved in 1 tbsp of warm water. This is a traditional ingredient that gives the buns their characteristic aroma and helps with rising. If you can find it, it will improve the buns significantly. Be careful not to add too much, as it can make the buns taste bitter.

Filling Ingredients:

* **Char Siu (Barbecue Pork):** 500g (approximately 1.1 lbs), diced into small cubes. You can buy pre-made Char Siu from a Chinese barbecue shop or make your own (recipe below).
* **Shallots:** 2 medium, finely minced, adding aromatic depth to the filling.
* **Garlic:** 2 cloves, minced, contributing savory notes to the filling.
* **Oyster Sauce:** 2 tbsp, provides umami and richness to the filling.
* **Hoisin Sauce:** 2 tbsp, adds sweetness, saltiness, and complexity to the filling.
* **Soy Sauce:** 1 tbsp, enhances the savory flavor of the filling.
* **Sugar:** 2 tbsp, balances the savory flavors and creates a sweet and savory profile.
* **Cornstarch:** 1 tbsp, used as a thickening agent for the sauce.
* **Water:** 1/2 cup (120ml), dissolves the cornstarch and creates the sauce.
* **Sesame Oil:** 1 tsp, adds a nutty aroma and flavor to the filling.
* **Cooking Oil:** 1 tbsp, for stir-frying the shallots and garlic.
* **Optional: Shaoxing Wine (Chinese Rice Wine):** 1 tbsp, adds depth and complexity to the filling (if you have it on hand).

Making Char Siu (Barbecue Pork) from Scratch

While you can purchase pre-made Char Siu, making it from scratch is incredibly rewarding and allows you to control the flavor and quality. Here’s a simplified recipe:

**Ingredients:**

* **Pork Shoulder (Boston Butt):** 1 kg (approximately 2.2 lbs), cut into long strips about 2 inches wide and 1 inch thick.
* **Char Siu Marinade:**
* 2 tbsp Hoisin Sauce
* 2 tbsp Honey
* 1 tbsp Soy Sauce
* 1 tbsp Shaoxing Wine (optional)
* 1 tbsp Sugar
* 1 tsp Five-Spice Powder
* 1/2 tsp Red Food Coloring (optional, for the classic red color)
* 1 clove Garlic, minced
* 1/2 tsp Ground White Pepper

**Instructions:**

1. **Marinate the Pork:** In a large bowl, combine all the marinade ingredients. Add the pork strips and ensure they are well coated. Cover and refrigerate for at least 4 hours, or preferably overnight.
2. **Preheat the Oven:** Preheat your oven to 350°F (175°C).
3. **Bake the Pork:** Place the marinated pork strips on a baking rack set over a baking sheet. This allows the fat to drip away and the pork to cook evenly.
4. **Bake for 30 Minutes:** Bake for 30 minutes, then flip the pork strips and bake for another 20-30 minutes, or until the internal temperature reaches 145°F (63°C).
5. **Glaze and Bake Again:** Remove the pork from the oven and brush with a mixture of honey and a little of the reserved marinade. Return to the oven and bake for another 5-10 minutes, or until the glaze is caramelized.
6. **Rest and Slice:** Let the pork rest for 10-15 minutes before slicing into small cubes for the Char Siu Bao filling.

Step-by-Step Guide to Making Char Siu Bao

Now, let’s get to the main event: making the Char Siu Bao!

Part 1: Preparing the Dough

1. **Activate the Yeast:** In a small bowl, combine the warm milk (110°F or 43°C) with the sugar and instant yeast. Stir gently and let it sit for 5-10 minutes, or until the yeast is foamy. This indicates that the yeast is active and ready to use.
2. **Combine Dry Ingredients:** In a large mixing bowl, whisk together the all-purpose flour, baking powder, and salt. If using ammonium bicarbonate, dissolve it in 1 tablespoon of warm water in a separate small bowl.
3. **Add Wet Ingredients:** Pour the yeast mixture and the dissolved ammonium bicarbonate (if using) into the dry ingredients. Add the shortening or lard.
4. **Knead the Dough:** Using your hands or a stand mixer with a dough hook attachment, knead the dough for 8-10 minutes, or until it becomes smooth, elastic, and slightly sticky. If the dough is too dry, add a little more milk, one tablespoon at a time. If it’s too sticky, add a little more flour, one tablespoon at a time. The dough should be soft and pliable.
5. **First Rise:** Place the dough in a lightly oiled bowl, turning to coat. Cover the bowl with plastic wrap or a clean kitchen towel and let it rise in a warm place for 1-1.5 hours, or until doubled in size. This step is crucial for developing the light and airy texture of the buns.

Part 2: Preparing the Filling

1. **Prepare the Char Siu:** If you haven’t already, dice the Char Siu into small cubes, about 1/4 inch in size.
2. **Sauté Aromatics:** Heat the cooking oil in a wok or large skillet over medium heat. Add the minced shallots and garlic and sauté for 1-2 minutes, or until fragrant.
3. **Add the Char Siu:** Add the diced Char Siu to the wok and stir-fry for 2-3 minutes, allowing it to heat through and absorb the flavors of the aromatics.
4. **Make the Sauce:** In a small bowl, whisk together the oyster sauce, hoisin sauce, soy sauce, sugar, and sesame oil (and Shaoxing wine, if using). Add the cornstarch to the water and stir until dissolved. Pour the cornstarch slurry and the sauce mixture into the wok.
5. **Thicken the Filling:** Stir constantly until the sauce thickens to a glossy, slightly sticky consistency. This should take about 2-3 minutes. Taste and adjust the seasoning if necessary. You may want to add a pinch of salt or sugar, depending on your preference.
6. **Cool the Filling:** Remove the filling from the heat and let it cool completely before using it to fill the buns. This prevents the dough from becoming soggy.

Part 3: Assembling the Char Siu Bao

1. **Punch Down the Dough:** Once the dough has doubled in size, gently punch it down to release the air.
2. **Divide the Dough:** Turn the dough out onto a lightly floured surface. Divide the dough into 12-16 equal portions. Each portion should weigh approximately 40-50 grams.
3. **Shape the Buns:**
* **Roll into a Ball:** Take one portion of dough and roll it into a smooth ball.
* **Flatten the Ball:** Use a rolling pin to flatten the ball into a circle about 4 inches in diameter. The center of the circle should be slightly thicker than the edges.
* **Fill the Bun:** Place about 2-3 tablespoons of the cooled Char Siu filling in the center of the circle.
* **Pleat and Seal:** Gently pleat the edges of the dough towards the center, forming a bun shape. Pinch the pleats together to seal the bun tightly. Make sure there are no openings, as the filling will leak out during steaming. A good technique is to make a circle with your thumb and forefinger of one hand, and then use the other hand to pinch and rotate the bun, sealing it inside the circle.

* **Smooth the Bottom:** Gently smooth the bottom of the bun.
4. **Place on Parchment Paper:** Place each assembled bun on a small square of parchment paper. This prevents the buns from sticking to the steamer basket.
5. **Second Rise:** Arrange the buns in a steamer basket, leaving about 1-2 inches of space between each bun. Cover the steamer basket and let the buns rise for another 20-30 minutes. This allows the buns to puff up slightly and become even fluffier.

Part 4: Steaming the Char Siu Bao

1. **Prepare the Steamer:** Fill a wok or large pot with about 1-2 inches of water. Bring the water to a rolling boil.
2. **Steam the Buns:** Place the steamer basket with the buns over the boiling water. Make sure the bottom of the steamer basket does not touch the water.
3. **Cover and Steam:** Cover the steamer tightly and steam the buns for 12-15 minutes. Do not lift the lid during steaming, as this can cause the buns to collapse.
4. **Turn off Heat and Wait:** After 12-15 minutes, turn off the heat and let the buns sit in the steamer for 2-3 minutes before removing them. This prevents them from shrinking due to sudden temperature changes.
5. **Serve and Enjoy:** Carefully remove the buns from the steamer and serve them immediately. Char Siu Bao are best enjoyed warm.

Tips and Tricks for Perfect Char Siu Bao

* **Use Warm Milk:** Ensure the milk used for activating the yeast is warm, but not too hot (around 110°F or 43°C). Hot milk can kill the yeast.
* **Don’t Overknead:** Overkneading the dough can result in tough buns. Knead until the dough is smooth and elastic, but not overly so.
* **Proper Rising:** Allow the dough to rise properly in a warm place. This is essential for the fluffy texture of the buns.
* **Cool the Filling:** Make sure the filling is completely cooled before filling the buns. Hot filling can make the dough soggy.
* **Seal the Buns Tightly:** Ensure the buns are sealed tightly to prevent the filling from leaking out during steaming.
* **Don’t Overcrowd the Steamer:** Leave enough space between the buns in the steamer basket to allow for proper expansion.
* **Don’t Lift the Lid During Steaming:** Avoid lifting the lid of the steamer during steaming, as this can cause the buns to collapse.
* **Let the Buns Rest After Steaming:** After steaming, let the buns sit in the steamer for a few minutes before removing them. This prevents them from shrinking.
* **Experiment with Flavors:** Feel free to experiment with different flavors in the filling. You can add mushrooms, water chestnuts, or other vegetables to the Char Siu filling.
* **Make Ahead:** You can prepare the dough and filling ahead of time and store them separately in the refrigerator. Assemble and steam the buns when you’re ready to serve them. Unsteamed assembled buns can also be frozen.
* **Freezing Instructions:** Steamed Char Siu Bao can be frozen for up to 2 months. To reheat, steam them for 5-7 minutes, or until heated through.

Variations of Char Siu Bao

While the classic steamed Char Siu Bao is a beloved dish, there are variations to explore:

* **Baked Char Siu Bao (Bo Lo Bao):** Instead of steaming, these buns are baked and have a sweet, crumbly topping. This version is also extremely popular.
* **Vegan Char Siu Bao:** Made with plant-based pork alternatives and a vegan-friendly sauce.
* **Spicy Char Siu Bao:** Add chili flakes or sriracha to the filling for a spicy kick.
* **Char Siu Bao with Different Fillings:** While traditionally filled with Char Siu, you can experiment with other savory fillings like chicken, beef, or vegetables.

Serving Suggestions

Char Siu Bao are typically enjoyed as a snack, breakfast item, or part of a dim sum spread. They pair well with:

* **Chinese Tea:** Jasmine tea, oolong tea, or green tea.
* **Soy Sauce:** For dipping.
* **Chili Oil:** For added spice.
* **Other Dim Sum Dishes:** Such as dumplings, spring rolls, and siu mai.
