I have two woks, a large wooden handled spun steel job from Atlas Metal Spinning in San Francisco, and a smaller cast iron one (I suspect it came from Japan, but I'm not sure).
I use them only occassionally, mostly for things that start large and wilt down to small. The problems I find are:
- On a gas stove they tend to be too hot in a ring around the center and not hot enough at the center where the oil runs to (on the clay stoves they were designed for they'd be hottest in the center).
- They take up way too much real estate on the stove top.
- Seasoning is very critical or you end up with a metalic taste in the phase where water is added and you cover it and let it simmer (not as much a problem in the cast iron one but you lose some of instant temperature control).
- they're a hassle to handle at the sink during clean-up.
I tend to do even Chineese stuff in the deep 10" coverable skillet.
