Hi,
In Dudley near where i live there is an Indian supermarket selling the steel high sided pans used in the trade for ?7 they are a little rusty on the bottom or around the side but are still a good buy, I have 7-8 woks that i used before i got a Ali frying pan from the same shop for ?8 they all have that long handle and can heat up and cool down fast,The problem with a wok for Indian cooking is that the liquid will not reduce as fast because there is not enough serface in contact with the heat that's the only deference between the two.
