I have noticed a lot of take away chefs are balding on top. Maybe this is due to the ignition of hot oil that you get from a jet engine burner underneath the wok

I tried this in my own kitchen and the only heat I got was from the Mrs when she had to clean the cooker!
It always amazes me how you can walk into a Chinese take away and there is some 80 odd meals on the board and all are available, anything from mixed grill to aromatic duck, and within 10-15Min's you are walking away with it. A lot of it must be precooked especially the curry sauce..
I had a wok that I seasoned by "burning" it till it went black and only wiped it clean with a piece of kitchen paper, but I still got food sticking to the bottom of it because I couldn't get it hot enough.
