Cha Shao Bao Chronicles Part 1: Trials and Tribulations

One purpose of this blog is to document my culinary endeavors. By endeavors I meant experiments, the good and the bad. It’s easy document the successful experiments, the ones that turn out well after the first attempt, like the strawberry lemon bars. It’s more difficult to document the experiments that fall short, the well... how should I put this... the failures.. Usually, I keep experimenting until I achieve the happy ending of a desired result. Unfortunately, Chinese steamed buns have me stumped so I’m wondering if anyone has any tips to make soft and fluffy steamed buns.

Last time I made cha shao, Steven and I ate it all before I could make bao. I promised that next time I made the pork, I would specifically set aside some for bun making. I have tried to make Chinese steamed buns many times in the past, during my inexperienced but ambitious teenage years, only to obtain less than stellar results. Emboldened by my recent successes with sticky buns and brioche (more on this later), I figured I was on a roll (I guess that pun was intended). Now that I’m older and wiser, at least I would like to think that I am, I figured I would have no trouble reproducing the soft and fluffy pristine white buns served at dim sum and Chinese bakeries. Boy was I wrong…

I must have looked at least a dozen recipes. Many recipes called for yeast raised dough made with a starter. So I decided to take this approach. I made a basic starter, then made the dough, let it rise, shaped it into buns, proofed, then steamed them. They looked a little… odd. Frankly they weren’t the prettiest buns on the dim sum trolley but looks aren't everything! I was hoping they would taste good. Well… the good news is that I did a decent job with the filling but the buns themselves tasted chewy and doughy, not the light and airy interior I was hoping for.

The recipe I used came from Ellen Leong Blonder’s Dim Sum: The Art of Chinese Tea Lunch. This seemed like a pretty decent recipe to me. The use of baking powder and baking soda would provide additional leavening power along with the yeast raised dough. The author states that the vinegar makes the dough more tender.

(Half of the original recipe)
Starter
1 tsp active dry yeast (I used instant yeast)
1/2 C lukewarm water
3 Tbsp sugar
3/4 C cake flour

Dough
1/4 tsp salt
1 1/2 tsp rice vinegar
1 C cake flour
1 1/2 Tbsp baking powder
1/8 tsp baking soda
1 1/2 tsp shortening (I used oil)

- The recipe is not entirely to blame for my poor results because I did not have any cake flour, so I substituted AP flour, which I suspect was mistake number one. The lower gluten content in cake flour would result in more tender buns. Also cake flour is bleached so the buns would be whiter than those baked with unbleached AP flour (mine were a bit yellow).

- Another possibility is that I overkneading the dough, leading to gluten formation. I used my Kitchenaid to knead the dough for a good 5 minutes. In retrospect this may not be good for bun dough because Chinese buns are not as chewy as oven-baked bread. Perhaps, less kneading the better.

- I also found some conflicting information about what leavening is best buns. Some say that using a yeast dough is unnecessarily because restaurants use only baking powder and cake flour. On the other hand, some sources attest that using only baking powder will yield bao that are less fluffy than those made with both yeast and baking powder.

- The grind of the flour also seems to be important. Some recipes call for Hong Kong flour, which is bleached, superfine flour. Maybe I'll look into buying this at my local Asian grocer but I think, cake flour would be an adequate substitute. Buns made entirely from cake flour are sometimes too lumpy, thus cake flour should be mixed with some AP flour.

- Some recipes call for milk instead of water. Maybe milk would create a more delicate dough.


What should I do for next time?
- Flour: Hong Kong/special bao flour? Cake flour? 50/50 cake and AP flour?
- Leavening: Yeast + baking powder or just baking powder?
- Liquids: Milk or water?
- Less kneading?
- Longer rise? Longer time for the starter?
- More baking soda + vinegar for an even higher rise?

And the final question? How do I get the bao to look like the ones served at dimsum. The bun itself looks like it blossomed, the filling isn’t entirely encased. Do I snip after I steam? I snipped before I steamed this time and it was pretty far from what they look like at dim sum.

I've had problems getting char siu bao, the baked kind, nice and fluffy. :(

I've got 3 suggestions for you.

1) But this sounds like you're making the white steamed kind that crack at the tops? If so, I'd suggest looking for a bag of "banh bao" flour at the Asian grocery store. That's basically the VNese version and should have directions on the bag.

2) My mom uses AP? flour, and again that boiling hot water, to create light and fluffy banh bao. The crack at the top happens naturally in the steamer when the dough rises.

3) The recipe on the back of Char Siu Bao Boy says 1 package yeast, 8 cups flour, 1 cup warm (not hot) water with 2 tsps sugar dissolved into it, 1/2 cup sugar, 1/3 cup oil, 1 tsp salt. Proof the yeast for one hour in warm sugar water. Mix dough. Let rise for 2 hours or until tripled in size. Punch down. Knead and divide into 2 dozen. Make bao. Let rise for another hour and then steam for 12-15 minutes.

Hope those suggestions help! And you can always mail them to me to "test" them out. :P

Not to totally self promote but by husband and I made amazing (and easy) cha shao boa not that long ago. My recipe is here. They were absolutely perfect and even reheated well the next day.

Hi Amy,

3 years ago, i tried making char siu bao too from several recipes online [i couln't find a book with a recipe]. Failed misserably on many occassions. Since then, i've had a phobia. hehe.

I saw a really good recipe online and have asked the author for the recipe since i couldn't find it on her archives. She kindly sent it to me. To be honest, i haven't really looked into making them again as i figured, i need a whole day free for my trial and error and another day to cry myself out. I've made considerable expense in the past making bao. I figured it's cheaper to go to a restaurant and order them. :)

One of the recipes i've tried in the past called for vinegar too stating that this will help the buns become whiter. I have to say though, that it didn't turn out white as expected. It was yellowish.

I'm looking forward to you creating the perfect bao and sharing the recipe.

In the meantime, i will search in my inbox for that recipe i was given and pass it to you. :)

I don't think the dough should have yeast - my mom looked through several of her Hong Kong books and none say yeast.

Do you have a pic to share of the bao? Now you are inspiring me to get in the kitchen and try...

WC,
I think the dough recipe I used might have been okay for baking, but I'm not sure.
I'll look for the banh bao flour next time I go to Ranch 99.
Oh I didn't know they cracked naturally, that's so interesting!
I'll try that char siu bao boy recipe sometime too!
Thanks so much for the suggestions!

Rachel,
Ooh, I noticed you used milk, I'll try that too.

Mae,
Oh I totally agree, getting the perfect bao is just traumatizing and disheartening.
I also read that vinegar helps make the bao whiter, but maybe that's in combination with bleached flour. My flour is unbleached so it didn't make a noticeable difference.
Thank you sooo much for looking for that recipe. I'll continue to work at the bao and hopefully I'll get it right! :)

Jaden,
Hmm that's interesting, I'll try making the dough with just baking powder and baking soda next time. I didn't take any pics, but I think there might be one or two in the fridge so I'll try to get a few pictures of those.

Too bad I'm not a baker, so can't give any tips. I'm just a cha shao bao eater :O
Can we take a look at your part 1 baos? :D
Come to think of it, the "cracked-like" top may be just to make it easier for vendors and customers to distinguish what bao is which - eg. lotus paste bao usually have a yellow dot on top, while cha shao bao is either a "cracked-top" or a red dot ? *lol*

Amy said...

Tigerfish,
I've been really lazy and haven't taken a pic of the (ugly) bao yet. :( I'll try to soon!
