Wok 99R The remedial class

post #1 of 17
Thread Starter 
Selecting a wok

There are lots of discussions about this out there so this will be a quick summary with some links to deeper discussions.


Carbon steel or cast iron. These are the two authentic materials. As you season and use these pans, they become more and more non-stick. And this type of surface protects the wok from rust and functions well at the high temps of wok cooking.

For carbon steel woks, consider the thickness of the material. Ideally I've been told, an average person shouldn't be able to flex the wok when you press from the sides. I don't know about that as all woks I've seen for sale in carbon steel have been thin enough to flex without too much effort. All the same, choose one you can flex the least.

Chinese cast iron woks will be a thinner casting than a western cast iron wok. The historic woks of china were cast iron. The thin cast iron heats much like a modern carbon steel wok, but is more fragile than carbon steel or thicker cast iron.. The thicker western style cast iron takes more time to heat up and is still fragile. These cast iron woks are heavy and the food is not usually tossed in these through shaking the handle as you often see with the carbon steel woks.

For cast iron woks, you want to choose a smooth even casting. The smoothness of the cooking surface is more important than the other surfaces.

Stainless steel--even layered and clad stainless steel, aluminum, enamel coated, non-stick coatings are all poor choices for a wok.They stick and are fussy at the temperatures involved. While you may see Ming Tsai and other chefs cook with some of these on cooking shows, remember that the pan manufacturer is sponsoring the program and it's about product placement. In his restaurant, Ming Tsai uses carbon steel.

Picking a handle

Carbon steel woks usually have a handle protruding from one side and a loop assist handle on the other side. Some will have two loop handles. This reflects a historic regional variation in the cooking of China. Northern China usually has the stick type handle and Souther China the two loop handles. A Northern Chinese cooking technique ( called pau or bau ) includes tossing the food in the pan by means of the handle. Southern China doesn't. This distinction is more historic than modern however.

Most carbon steel woks have the stick handle. It can be wood but is more often metal. Check the attachment strength, There shouldn't be flex through the handle or attachment point. Even wood handles can get hot in wok cooking so expect to use a hot pad.

Now and then you'll see a vertical stick handle on a wok. I've never tried that particular kind of handle.

Cast iron woks usually have two small ears or handles cast integral to the wok. Some do have stick handles, usually the thinner Asian variety of cast iron which aren't as heavy as their western counterparts

Choosing a Shape

There are two basic wok shapes: round-bottom and flat-bottom.

The classic wok is dished and round throughout. This shape doesn't work well on many western stoves but is ideal for concentrating heat in the bottom of the pan. For Western stoves, round bottom woks need a wok ring to sit stable and safely on the stove. Gas stoves tend to work better for round bottom woks than electric,

flat-bottom woks were designed for Western cook tops. They work on gas, electric, glass tops and other common household stoves. They don't work as well as a round bottom wok, but there are times they can be a reasonable compromise, particularly for the glass top stoves. They often require some adapting of classic wok technique to work their best.

In some cast iron woks, the casting will be flat on the bottom but completely round inside. This is a nice feature for western cook tops giving you both the flat-bottom and round cooking surface. Cast iron woks will probably not be smooth enough on the bottom for a glass top stove. They will scratch it.

There is a fair amount of disagreement between users of round and flat-bottom woks. I strongly prefer the round bottom woks, even on electric coil burners, but respected Chinese cooking authors such as Grace Young prefer flat-bottom woks for all home stoves.

Choosing A Wok

Choosing the size

For most home cooking, a 14" wok is a good size for most households. Big enough to hold a reasonable quantity of food without crowding out the stove or storage options. Also the right size for a whole chicken or duck or fish. Comfortable to work in without making a mess.

Seasoning a wok

Seasoning carbon steel is very much the same as seasoning cast iron.

The wok is cleaned of protective grease, wax or other production coating.

A fat/oil of some type is carbonized by high heat into the surface of a wok forming a black, less-reactive non-stick surface usually referred to as the patina. Cast iron generates a tougher thicker patina than carbon steel.

There are some Chinese traditions about seasoning a wok, Most involving the use of Chinese chives and pork fat. The wok might be scrubbed with the woody stems to clean and sanitize the metal. Most end up stir frying the chives in the wok at some point. It's often said to remove the metallic flavor from a a new wok.

In practice, there are many ways people season woks.Here are two common ways.

Stovetop method

Wash the wok with hot soapy water and steel wool or green scotchbrite. Rinse well and dry.

Rub a thin even coating of shortening all over the metal inside and out. Or spread oil thinly and evenly over the wok with a paper towel.

If you have a burner on your grill, consider doing next step outside. Alternatively, Turn off your smoke alarm or tape it over with plastic wrap or plastic bag. Then turn on the fan and open the windows and doors.

Heat the wok on high heat on the stove. It will smoke as it gets hot. The bottom will darken faster than the rest. Heat it about10-15 minutes, then let it cool down. You may want to keep wiping it with a paper towel to keep oil from pooling in the lower part of the wok. Hold the paper towel with tongs to protect you from the heat. Uneven layers of oil or fat cause sticky spots and uneven seasoning.

For a more even seasoning on a carbon steel wok, take the time to tilt the wok into the heat and get a darker seasoning on the upper edges of the wok. The wok will continue to take on darker and darker patina with use.

Oven method for cast iron

Cast iron woks can be seasoned in the same way as carbon steel woks, but also in the oven or grill. I prefer the oven method.

Heat the oven to 500 degrees. Put a rack on the lowest level and another rack right above it. Put a sheet of foil
on the lower rack if you wish. The intent is for any dripping oil to fall on the foil rather than your oven floor. In practice, if you put a light coat of oil on, any drips will burn off before you're done. If this is your first time seasoning cast iron, use the foil as backup from too much oil.

Wash the wok with hot soapy water and steel wool or green scotchbrite. Rinse well and dry.

Rub a thin even coating of shortening all over the metal inside and out. Or spread oil thinly and evenly over the wok with a paper towel.

Put the wok in the oven upside down. This prevents any fat from pooling in the bottom of the wok and messing up the seasoning.

"Bake" the wok for 1 hour. Turn off the oven and let it cool undisturbed. This will take hours so consider doing this in the evening and letting the wok cool overnight. This also lets the smoke dissipate while you're elsewhere. Again, open windows are helpful.

I've found this method best for seasoning all cast iron. It always comes out with an even dark black layer. Most of the manufacturer recommended methods leave the cast iron yellow or brown and often sticky as the fat wasn't completely carbonized.

Accessories and utensils


Wok ring

A tapered ring, usually with holes around the edge for air flow, used to stabilize a round bottom wok on western style stoves.


A 14" wok should have approximately a 13" lid. Then general rule for sizing a wok lid is 1" smaller diameter than the wok itself. Wok lids don't fit tightly like you may be used to on western cookware but are still useful and inexpensive. They are usually highly domed and this is a good shape for some of the other ways you can cook in a wok.These are generally of stamped aluminum with a wooden handle at the center.

Spatula or shovel

This is a round tipped spatula with raised sides and back.It's usually about the same length as the wok is across (14" for most home cooks). The rounded front edge matches the shape of the wok. This is a bit problematic in the flat-bottomed wok which isn't evenly rounded everywhere. Still, where the flat-bottom transitions to the rounded sides, this becomes useful.


Sometimes called a skimmer, a large brass or stainless steel wire disc-shaped basket for straining out fried, blanched or boiled foods. I prefer the 6" size over the smaller 3" size.

Cooking chopsticks or tongs

Long bamboo chopsticks are used for selecting items or pushing items into the spider. I'm not handy with chopsticks so tongs are a good substitute.

Useful Accessories and utensils


Most often a broad oval shape, the oval matches the curve of the wok. It's usually about the same length as the wok is across. As a home cook I find the ladle less useful than the spatula. Most professional wok cooks use the ladle over the spatula. In their pro kitchen, they'll dip the ladle in various oils, seasonings, stocks and so on to add to the wok they're cooking in. They usually drag it from the back towards the front.

Steaming baskets

Bamboo baskets, usually two steaming layers and a lid. You partially fill the wok with water, not up to the level of the basket. The basket rests on the wok above the boiling water catching the steam and directing it around the food.
How to use Asian bamboo steamer for steaming asian food recipes


A round rack, often with legs. Heatproof plates are set on the rack as for steaming but with the wok lid to hold the steam. Or for smoking food as in Tea Smoked Duck.

Stir frying in a wok

The stir fry technique is suited to the shape and high cooking temperatures of a round wok. This too is often discussed and will only be touched on briefly here.

Classically, there are two stir-fry techniques. Chau, usually westernized as chow as in chow mein. And pau (pao, bau), A very high heat pan toss method but also seen as a more vigorous stirring technique as in Kung Pao chicken (more authentically gong bau chicken not counting diacritical marks). Stir frying - Wikipedia, the free encyclopedia

Outdoor Stir Fry Stove - Stirfry Techniques - Chao and Bao. (some good videos too)

These and other techniques are briefly discussed at:
Outdoor Stir Fry Stove* - Other Cooking Techniques.

Basic preparation for wok cooking

All food and seasonings are cut and measured and at hand so they're ready to go as you're cooking. There is no time to do additionally preparation and the wok needs your undivided attention.

Often some ingredients are seasoned and cooked apart from other foods, then combined right at the end. This allows each of the ingredients to have a different texture and flavor than other ingredients in the same dish. This variation in simultaneous flavor and texture is a hallmark of Asian cuisine.

Stir frying in a wok at home

As you stir through a round wok, the pieces tumble and turn themselves as they fall back to the bottom. In contrast, the western saute pan and flat-bottom wok act more to push the food around when stirred with the spatula. And one pass through the center will not agitate all the food as it will in a round wok. You have to chase the pieces around more in a flat-bottom wok.

The other issue for home cooks is that they generally don't have the high heat of restaurants or of the original stoves for woks. So food tends to cook slower, often releasing and accumulating liquids rather than quickly boiling them off. Further, the food doesn't sear in the time it's in contact with the pan so it doesn't have the flavor.

Two adaptations to classic technique are important for cooking in a wok at home. Cooking smaller amounts in batches and letting the food sit a minute or two to sear and pick up the flavor of wok style cooking.

Because Asian food often cooks ingredients separately then combines them right at the end, it is well suited to cooking in smaller batches. The goal here is to keep the pan from losing too much heat as ingredients are added. There should be a continuous and hard sizzle sound. You'll have to experiment with your wok and stove to see how much of what ingredients it can handle without too much of a heat loss.

Besides working in smaller amounts, you may need to let the food sit for a couple of minutes. This is particularly important with meat where you need to put in the wok in an even layer and let it pick up some color and flavor. If you stir it, the meat will gray more than brown and often loose too much heat to each new uncooked face of meat it meets. Let it sit a minute or two ,then stir fry another minute or two. Some foods such as shrimp won't need as much undisturbed time.

With a round bottom wok on a western stove, you may have to repeat the stir and rest technique a bit as the upper parts are cooler than the bottom especially on home stoves.

Fried rice is another dish that benefits from letting the rice toast in the wok a bit undisturbed. Stir and let toast a bit, then repeat until the rice is right. Let your nose guide you.

Chinese Food Theory

The Chinese, and to some extent the rest of Asia, have a different view of food. As already mentioned, they usually have a greater contrast of flavors and textures in one dish than is common in the west. They see their health as tied to the foods they eat in a more direct way. And some foods are reputed to have particular health effects. Similarly, they choose different foods in a meal to balance the elements of nature and the particular yin and yang elements of the meal. These tie back in to their view of how the food will affect their health. One can delve deeply into this but it's not absolutely necessary to creating a good Chinese meal.

But it does introduce some ways to put together a Chinese meal at home. Often in a Chinese restaurant, westerners will construct a meal of various stir fried dishes as well as fried rice that arrive at the table all at once. You're not going to be able to do that with just one wok and one cook. And neither do the Chinese.Rather the meal will have dishes cooked in various ways, again to bring in contrasting flavors and textures as well as reflect the realities of kitchen and cook capacity. Include soups, fried dishes, braises and steamed dishes which can be cooked in your other pots and pans.

great post! Been trying to force NRatched to research a little more. We were at the Hong Kong Supermarket yesterday and found some nice carbon steel round woks, with 2..."D" handles for 7.99 rings were 1.99.

perfect thread for NRatched.

I'll have to amend my statement about woks and flexing. I found one today that didn't flex. Not pretty, basically a spun carbon steel wok that had been peened. It was definitely a thicker and heavier gauge of steel.

They called it a "pow-wok" I suppose after the pau technique.

Wholesaled and labeled through these people, www.greatchinaproducts.com, it seems it's also available at retail on the 'net via the Wokshop the wok shop: selling woks for 30 years The store I was at had a better price.

do you have any pictures of your wok setup on a gas stove like mine?

NRatched is actually cooking asian tonight, and since I just ordered a misono UX-10 and some stones to the tune of 350, I'm going to pick her up a wok on Wed.

I don't but could take one. What are you looking for in the pic precisely? This would help me pick a vantage point.

My stove has the wells for the burners like yours, but has a continuous grate arrangement so it might not show what you're looking for.

All right. I took pics this AM. Unlike you, my stove is far from immaculate.

On the stove from the front.

Normally for a gas stove, they recommend using the wok ring upside down from how I have it oriented above. But I've found I get a hotter wok with this orientation.

The wok ring from directly above. This gives a better view of how my burner well is dished and conflicts with the wok ring, particularly in front.

And some pix of seasoning the pow wok. I decided to pick one up and give it a go. It was inexpensive so no big deal.

I scrubbed it out and took this pic of my wok family. I put the label back in for the pic. On the left is my 18 year old wok. The new pow wok is in the middle and my cast iron wok is on the right. I've taken to doing my wok cooking outside on this three burner stove. Each burner has 30,000BTU capacity and I get a much better stir fry from this stove.

Now on to seasoning. The wok on the burner.

Wiping the oil around evenly as it heats.

The dark seasoning starts to form.

First seasoning complete. The wok is still smoking, perhaps you can see some wisps on the far edge. Notice how it's black, then fades into browwn and gold on the upper edges. Those edges will darken up some more with use and become black.

I've changed internet hosts and so all my picture links have broken. Sorry.

I also read a new trick in Eileen Yin Fei Lo's Mastering the Art of Chinese Cooking. She notches a wok ring to fit the grate of her stove. Adds stability and gets a better fit of the wok to the stove.

When I ordered the wok I have coming from The Wok Shop, I ordered a bunch of other stuff. Ladle, spatula, perforated scoop, brass wire and mesh skimmers, bamboo steamers and whisks, two lids (one for the flat bottom wok i bought last week), and last but not least, three wok rings. What's cool is the whole deal was $121.00 bucks plus $17.00 for shipping. Less than an All-Clad frying pan. Awesome.

Two of the rings are for experimentation. I have these Knipex bolt cutters that are going to go through the aluminum rings with ease, and plan to cut notches in them to fit down on the grates of my gas range. I thought of it last night before reading this post. :D

I'm thinking of buying a flat bottom carbon steel wok but somewhere on youtube I saw some posts mentioning that after a year it "warps" ( i don't know what that means) and they toss it away. does it really last a year? or are the people just not taking care of it properly or could have done a simple fix to it. If it really lasts for a year then I'll just stick with my cast iron.

Lots of variables in the flat bottom wok situation. Quality of the initial wok of course and how hot your heat source is being the two biggest.

As woks are fairly thin material compared to standard heavy pots and pans it's certainly possible to warp them. Restaurants do so regularly with their high heat stoves, but the common fix is to just pound it back out. Easier with a round wok than a flat though.  Breath of a Wok shows Ming Tsai hammering out the woks at the end of a shift (as I recall, may have been someone else).

For a gas stove, the warp won't matter much. for a glass top, or other electric or induction, warping is probably a bigger problem.

The Wok Shop(San Francisco) is great, definitely have steered me in the right direction. Using a flat bottom wok on a residential range can be a little frustrating, you just won't get the heat that you need to do it right.  I got rid of mine and now for small meals, I just use my 12" steel skillet, get it hot as hell and go for it.  When I get ambitious or with a crowd (more than 2), I have my 60k Btu burner outside.  Now THAT works.  Warping: not had a problem with that.  I always clean it on the burner with a small cup of water and scrape off any fond.

This is excellent and very timely for me as I am about to teach a stir-frying class. My wok is ancient but heavy gauge and should last forever.Wok.jpg

 Anyone know the actual temperature of the metal for an average stir fry?
I'm thinking of getting  an induction burner which have some models that can go up to 440F for the 200$ models and 390F for the 100$ models. then have a flat bottom carbon steel wok to cook on it. There are round bottom induction stove tops but 3k$ is just too much.
I know its an high enough temperature to achieve the leidonfrost effect but what about the wok hay?

You should be able to achieve wok hei in a flat bottom wok. Mid 400s is where most start stir-frying as that's the extreme temp of the better oils for stir frying. Where they start to smoke or break down. Temps drop of course when you add food, and it becomes the balancing act of how much food can your heat source properly cook.

I'd prefer the 440 over the 390 personally.

If you're including passing through oil as part of your wok technique, round bottom works are better for that.  I too noticed those price differences for the induction burner and then there is also the issue of how closely your wok fits the curve of the induction surface.

Think about cooking height. Those induction burners add 6ish inches so a dropped counter or other lowered surface for the induction unit would be nice for comfort.

Without going to the point of customizing my kitchen, I've had good results cooking over high output outdoor burners on the back porch, .Even in the winter, the time cooking is so fast it's not a big deal to wok cook outside.  I'm using a stove from Camp Chef with 30,000 BTU per burner. Does a nice job of stirfrying.
