Images of eating Char Siu Pao with my parents at a bustling dim sum shop in Ipoh still flashes vividly in my memories after more than forty years.
This childhood memory is sweet and nostalgic. The excitement of waiting for the waitress taking out the steamingly hot Char Siu Pao from the dim sum trolly made me smile in reminiscence.
The soft and tender bun, the oozing soy based thick gravy and the meaty filling weaving seamlessly into a perfect culinary masterpiece. Today, Char Siu Bao is still taking the center stage of all dim sum spread in every Chinese restaurant.
Char Siu Bao or char siu Pao ( 叉烧包) is the most famous classic Cantonese dim sum. Delectable and exotic, a meal of dim sum can truly be one of the best you’ve ever had.
Dim sum is a delightfully Chinese delicacy usually served with tea. It literally translates to "touch the heart," which means "take what your heart picks." The culinary art of preparing dim sum has been long-held by the Cantonese in Southern China.
Cha Siu Bao is a bun filled with barbecue pork. Barbecue pork is called Char Siu (or char siew) in Chinese, hence the name Cha Siu Bao. This pork bun is generally eaten from morning to early afternoon and usually served with Chinese tea, which is called yum cha ( drinking tea ) by the people in Hong Kong. Nowadays, you can also find barbecue in many lunch menus in Chinese restaurants all over the world.
Note: You will notice that I use chicken in the recipe. Char Siu Bao is filled with pork traditionally in China. However, there are some restaurants filled it with chicken meat, which is equally delicious. If you like to use pork, just substitute the chicken with 80% lean pork and 20% pork fat. It will turn out fantastic.
Char Siu means barbecue meat, which can be any meat. There are stores in most Chinese community sell this type of barbecue meat as the filling of the bun. You can also make it by yourself. If not, follow this recipe, and it will turn out just like using the barbecue meat.
The buns are steamed by high heat to let the dough expand rapidly and burst open at the top, partially revealing the meat filling. This steamed pork bun is best to serve hot straight from the steamer.
The buns of the classic recipe are filled with the stir-fried trimmings of roasted pork butt which is slightly fatty but tender. You can use chicken meat instead of pork so that it is suitable for people of all races and religions.
The technique of making the dough is similar to that of making bread. The main difference is to use, multiple types of leavening agents to achieve the tender, bouncy and bursting surface. Of course, it is steamed, not baked. The buns are cooked in less than ten minutes due to the intense heat generated by the steam in the enclosed steamer.

How to make Char Siu Bao- video demonstration (3.57 mins)
Note: Some techniques are easier to understand by watching the video.)
How to make Char Siu Bao like the professional chef
1. The meat filling
How to prepare the juicy filling
You can use more water than stated to cook the filling. It is important to cook it until the gravy is thick enough. If it is too thick, the filling will not be juicy. If it is too diluted, it is difficult to seal the ingredients in the dough. I have water as part of the ingredients to cook the filling in the recipe, but you may notice that I did not add any when I demonstrate in the video. This entirely depends on you. As long as the consistency is just like what I show in the video, it should be good to go.
What other meat is suitable besides pork for making Char Siu Pao?
Traditionally, barbecue pork ( char siu 叉烧) is used. You can use chicken breast meat as it is suitable for all races and religion. The flavor is very close to that of pork.
When you prepare the filling, there are a few points that you need to note:
1. Sauté the onion until it turns fragrant before adding the chicken meat.
2. Combine the cornflour with water to form a slurry before mixing it with the meat, or you can just mix EVERYTHING together. It really does not matter.
2. The pastry
Choose the best flour to make the Char Siu Bao
Use the right type of flour to make Char Siu Bao. I have seen different types of flour suggested by chefs, and I would like to elaborate a little on this subject.
The suitable types of flour for making Char Siu Bao is Pao flour or Hong Kong flour. The low percentage of protein of these types of flour will produce the optimum amount of gluten required for bouncy and soft buns. Both are bleached and can produce white buns normally seen in dim sum stores.
The difference between Pao flour and Hong Kong flour is that yeast is added to Pao flour, and it is not added to Hong Kong flour. You can add more dry yeast even if you use Pao flour just in case the yeast is inactive. If you have difficulty to get Pao flour, you can use cake flour as it contains a similar percentage of gluten, but the color of the Pao will be slightly yellowish.
3 Leavening agents to ensure it is soft and tender
There are three leavening agents used in the recipe.
Both baking powder (sodium bicarbonate) and yeast are used to achieve the bouncy and soft texture. Both are quite common in baking, but you may be unfamiliar with ammonium bicarbonate.
Ammonium bicarbonate ( commonly known as 臭粉 In Chinese ) is a leavening agent nowadays seldom used. It is also hardly used in any western baking products. It is used in the recipe to serve a special purpose- to produce the signature bursting surface of the Pao. The professional finishing of Char Siu Bao should be burst ( 开花 ) into three or four parts on the surface, much like the crevices on top of a hot cross bun. It is created by using ammonium bicarbonate instead of cutting lines on the surface as for bread.
You can omit ammonium bicarbonate as it does not contribute to the flavor of the Char Siu Bao. The only difference is that the surface may not burst into parts, the ‘professional’ finishing of Char Siu Bao.
The right way to knead the dough
Dough making is quite similar to making bread. Some chefs prefer to prepare a starter just like for making bread, as in this recipe. In this case, part of the flour will be used to prepare the starter. The flour will ferment longer which results in a better flavor.
Some less common ingredients in dough making explained
Is lye water necessary in the recipe?
Lye water ( 碱水 )- some recipes suggest adding lye water into the dough. Our recipe has no lye water. There is a problem if you add too much lye water as it will leave a bitter taste to the Pao. I do not use lye water in this recipe.
How about include wheat starch in the recipe?
Wheat starch ( 澄面粉) can be added to the recipe in a smaller amount. Wheat starch can produce a very soft and bouncy texture since wheat starch has no protein. The Pao made by following this recipe is quite soft and there is no need to add wheat starch.
How about adding vinegar to the recipe?
Vinegar is added for a purpose. Since wheat starch has no protein, and Pao or Hong Kong flour has a low protein content, the development of gluten that contributes to the strength, and texture will be limited. The ideal pH for gluten development is 5-6. This will encourage gluten development and produce a more extensible (easier to stretch) dough. Vinegar helps to maintain the pH of the dough so that it is not too alkaline due to the use of baking powder and ammonium bicarbonate. This will produce Pao with good texture and yet is bouncy and soft.
However, I have tested my pao recipe and noticed that as long as the oil and the flour are white, there is no need to add any vinegar. Therefore, I do not include vinegar in my recipe.
How to make the bun whiter than snow white
A number of recipes suggest that vinegar can whiten the dough. However, we have tried to make Pao with and without vinegar, and the color of the Pao is identical.
The answer to the snowy white Char Siu Bao lies in the color of the flour and oil that you use. Hong Kong flour and Pao flour are bleached and will produce white Pao. If you use the standard cake or all-purpose flour, the color of the Char Siu Bao will be slightly yellowish.
The type of oil you use will affect the color of the Pao. If you use vegetable or animal oil, the Pao will be slightly yellowish. We use shortening of soy origin to produce a snowy white Pao. If you want to use a healthier alternative, use unbleached flour and vegetable oil instead of bleached flour and shortening, The flavor will not be affected. But the Pao will not be as white as those from a professional dim sum shop.
3. Wrapping, steaming, and storage
How to wrap the filling- best to watch the video
The best way to understand how to wrap the filing is to watch the embedded video. The following is the summary:
1. Roll out the dough to a round shape, but leave the center slightly thicker as this is the bottom part of the Pao.
2. Wrap and pleat the dough to seal the filling.
3. It is not necessary to seal the Pao dough tightly, Just folding and slightly squeezing with your fingers is sufficient. This is different from shaping the pie crust, where the line formed by you will stay even after baking. Most of the folding lines will disappear after steaming due to the strong leavening action by baking powder and yeast. It is (traditionally) acceptable if the dough is 'erupted' due to the rapid expansion of volume during steaming and review part of the filling.
The right way to steam the Char Siu Pao
1. Place each Pao seal side up on a small piece of oiled baking paper.
2. Place the Pao in a steamer tray. Make sure the water is boiled rapidly.
3. Steam the Pao on high heat for eight minutes with plenty of water and covered at all times during the entire steaming process.
4. Please note the bigger the paos, the longer you need to steam them. There will be a starchy taste for paos that are not fully cooked. It is harmless to steam a little longer than suggested.
How to keep the Char Siu Pao for an extended period
1. You may want to make a large batch of Char Siu Bao but and keep part of it. The best way is to steam only the number of pao you want, and froze the raw pao (with the cooked filling inside). The is the same way how to keep the raw dough of bread in the bakery.
2. Place the freshly wrapped bao on a large baking tray. Put the tray of bao in the freezer until the baos are hard enough. Keep them in a plastic container and keep in the freezer until you want to steam them.
3. Arrange the frozen bao on a steamer tray and wait until it is at room temperature. You can now steam the bao just like the fresh one.
