Tips on Chinese cooking techniques

162 posts in this topic

dmreed - this same thing happened to me a couple of days ago. And it made me confused too. My sauce because watery again after 10 minutes (I used potato starch to thicken it).

glad to hear that it is not just me! but sorry you have the same problem!

maybe someone can explain why this happens and what to do about it.

Yesterday I made some sticky rice wrapped in lotus leaves. So I had a fair amount of mushroom and dried prawn soaking liquid left over. I used a mixture of these two instead of chicken stock in a brocelli with ginger and oyster sauce dish. It worked a treat.

I also keep the soaked chinese mushroom stems in the freezer to enhance stocks etc.

Parma ham ends that you some times buy very reasonably from deli's make a great addition to a chicken stock if you want to make some thing very special.

Edited - cos I forgot to mention I freeze all my ginger peeling to add to stock also, seems a shame to waste them because they are very flavorfull :wink:

After adding the corn starch and water to a dish to make the sauce, while heating and stiring the sauce thickens as expected but, after about 3-5 minutes, it becomes non-thick (runny) again. Why does this happen and what can be done to prevent this from happening?

The ingredients are still cooking even after you turn off the heat, cooking means leaching out moisture from your meats and veg., hence the dilution of the sauce. Can't be helped, happens to the best of us. :wink:

In addition to the release of liquid that Ben Hong pointed out, Harold McGee states that boiling and stirring can thin out starch-thickened sauces by shattering fragile starch granules into smaller particles. The thicker the sauce, the more dramatic the thinning effect. Similarly, acidity can thin a sauce by breaking starch molecules into smaller fragments.

McGee rates corn starch as having “moderate” stability to prolonged cooking; arrowroot-thickened sauces are less prone to thinning out.

Edited to clarify.

thanks folks, would using more corn starch reduce the problem?

Yes...and no. You really, really do not want a gloppy dish, a better solution is to use less liquid. If your dish is a stirfry, the amount of liquid in the wok should be barely discernable at the end, just at the moment of adding thickening. Look up wok hei in this forum if you really want to achieve that kind perfection in a dish.

Unlike western style dishes where the gravy or sauce is poured onto the food, the Chinese style requires that the sauce be made as an integral part of the dish, and as such will suffer the dilution caused by leaching out of liquids from the solid ingredients. Perhaps that why Chinese dishes should be eaten soon after it leaves the wok (to enjoy the wok hei); and that's why in most restaurants catering to the Chinese, dishes come out sporadically, as they are done, instead of all at once.

while viewing the video series Chopstick Bowl (Chinese Takeout), the cook frequently blanches/parboils both the meat and vegetables (separately) before stir-frying for common recipes which I have seen just stir-fry the meat and vegetables separately.

is this a common practice? maybe for some areas of China or styles of Chinese cuisine?

I think I asked too soon.

it seems that the series is (as indicated!) dedicated to fast food takeout type recipes and cooking.

the reason for blanching the ingredients is to allow rapid cooking fo the final dish....for main dishes, e.g., chicken and broccoli, essentially the sauce is prepared, the ingredients blanched, then when ready to prepare the dish, the wok is heated, the sauce is added to the wok and heated, then the blanched ingredients are added and heated until ready to serve!

this seems to be a little faster than the usual food prep before starting to stir-fry. I might even try this technique when I have some prep time a while before I need to cook!

I am still interested to know if this is a common practice or style of cooking.

Again, there are no hard and fast rules. The methods you describe are used by second and third rate take out places for a less discerning clientele. Nothing wrong with it, it's just not common in household cooking or in finer restaurants. Hard veggies like broccoli and carrots, etc can be blanched but NEVER, NEVER meats and fish...nor tender leafy veggies. Meats and fish should get the benefit of carmelization in oil over high heat. Please refer to wok hei.

thanks, that is what I thought and I do try to achieve wok hei when I stir-fry...I am trying to learn how to cook smaller quantities because even the "hot" biggest burner of my stove is not really that powerful :>(

Hi Gang,

In addition to the wealth of information on this site some of the best tips (or should I say entire education) I have found on chinese home cooking is at this site http://www.tigersandstrawberries.com. There is an amazing amount of chinese cooking information there for beginners and experienced cooks. Unfortunately due to personal issues the author recently stopped adding to the site but she is leaving this incredible resource permanently available to all. The site was invaluable to me a few years ago in instructing how the home cook can come close to achieving that elusive wok hei using a wok on standard cooking appliances.

Below I have listed the posts and topics from the site that are most relevant to chinese cooking:

The typical Cantonese style of "plain steaming" - just the fish with some ginger and nothing else - you add more ginger and some green onions and splash fuming hot oil on top then add some soy sauce.

Then there is Cantonese style steamed fish that you steam the fish with fermented black beans and ginger. This dish can be consumed as is or some can add the ginger/green onions and splash fuming oil on top at the end too.

Not wise to heat sesame oil - the smell is bad and heating turns the oil taste to bitter.

Cutting ginger into slivers, shreds or to mince it or to grate it is a matter of preference.

There is a third way of steaming fish, especially if the fish is extra oily or too "aromatic". Panfry and brown with a little soy sauce first, then steam normally.

I (being Cantonese, specifically Toysanese) have never used sesame oil on any steamed fish. As Ah Leung says once you heat it to a sizzling temp., it smells and tastes awful. (Must be the technique of those barbaric Northerners tongue.gifwink.gifunsure.gif )

Hmm. I use sesame oil frequently as a component in the mixture used to *marinade* the fish before it is steamed. I don't heat sesame oil to pour over the steamed fish, but the use of sesame oil in the preparation of steamed fish Cantonese-style is NOT verboten.

So I take it double boiling is the preferred method of making tonics out of all the herbs and various dried creatures I see in the Chinese Medicine places around here, I've only had a very limited range of things in soups and hotpots - but it makes more sense now what can be done with those dried sea cucumbers and mysterious animals in those shops.

I was actually just in one this weekend, they had packages of various leaves and herbs and roots that had - of all things - the molted shells of Cicada.

If I ever have trouble with my hearing - I know just what kind of soup I'll be making.

No, "Dun Tong" is NOT just for "making tonics out of all the herbs and various dried creatures" that you think of. It's a common technique for making flavorful, tasty, wonderful soups using all sorts of ingredient combinations. Yes, many are "tonic/medicinal" in inspiration but many are not. Double-steamed "Lou Wong Kua Tong" or "Ham Choy Kai Tong" for example would have little "medicinal" aspects to them. It's just a way of extracting the taste from ingredients by cooking them at a temp just below the boiling point of water, in a vessel that contains all the ingredients and traps all the juices etc. [You typically do "Dun Tong" in a heavy ceramic "pot"/"bowl" with a close-fitting equally heavy lid] In a sense, it's an old way of doing something in a "sous vide" type of cooking.

      I was recently asked by a friend to give a talk to a group of around 30 first-year students in a local college - all girls. The students were allowed to present me with a range of topics to choose from. To my joy, No. 1 was food! They wanted to know what is different between western and Chinese food. Big topic!
       
      Anyway I did my best to explain, illustrate etc. I even gave each student a home made Scotch egg! Which amused them immensely.

      Later, my friend asked each of them to write out (in English) a recipe for their favourite Chinese dish. She has passed these on to me with permission to use them as I wish. I will post a few of the better / more interesting ones over the next few days.

      I have not edited their language, so please be tolerant and remember that for many of these students, English is their third or fourth language. Chinese isn't even their first!

      I have obscured some personal details.

      First up:

      Tomato, egg noodles.

      Time: 10 minutes
       
      Yield: 1 serving

      For the noodle:

      1 tomato
      2 egg
      5 spring onions

      For the sauce:
       
      1 teaspoon sesame oil
      1 tablespoon sugar
      ½ teaspoon salt

      Method:

      1. The pot boil water. At that same time you can do something else.

      2. Diced tomato. Egg into the bowl. add salt and sugar mixed. Onion cut section.

      3. Boiled noodles with water and cook for about 5 minutes.

      4. Heat wok put oil, add eggs, stir fry until cooked. Another pot, garlic stir fry the tomato.

      5. add some water to boil, add salt, soy sauce, add egg
       
      6. The tomato and egg sauce over noodle, spring onion sprinkled even better.
       


      More soon.

      I just bought these greens from the neighborhood Asian grocery. Had them once in China as a salad, and they tasted exceptional - a bit peppery like arugula, yet much more subtle and fresh, with hints of lemon.
      Store lady (non-Chinese) could not name them for me other than "Chinese greens".
      Any help identifying them is greatly appreciated

      China's plan to cut meat consumption by 50%
       
      I wish them well, but can't see it happening. Meat eating is very much seen as a status symbol and, although most Chinese still follow a largely vegetable diet out of economic necessity, meat is still highly desirable among the new middle classes. The chances of them willingly giving it up, even by 50%, seems remote to me.

      I have been asked to make Chinese Bow Tie desserts for a function. However, I have never made them, but using Mr Google, there are a number of different recipes out there. Does anybody have a decent recipe which is tried and tested? - these are for deep-fried pastry which are then soaked in sugar syrup.

      My son married a lovely young lady from Yakeshi, Inner Mongolia, China.   Mongolian: ᠶᠠᠠᠠᠰᠢ ᠬᠣᠲᠠ (Ягши хот); Chinese: 牙克石; pinyin: Yákèshí
       
      We had a wedding in the US but her family also wanted to have a traditional wedding in China.  DH and I have never being to China so this was an exciting opportunity for us!  We spent a few days in Beijing doing touristy stuff and then flew to Hailar.  There is only one flight a day on Air China that we took at 6 in the morning.  Yakeshi is about an hour drive from Hailar on a beautiful toll road with no cars on it.  I wish we took pictures of free roaming sheep and cows along the way.  The original free range meat.
       
      The family met us at the airport.  We were greeted with a shot of a traditional Chinese spirit from a traditional leather vessel.  Nothing says welcome like a stiff drink at 9 AM.  We were supposed to have a three shots (may be they were joking) but family took pity on us and limited it to one only.
