The Wok Hey's not it. I have a well seasoned carbon steel wok and even if I get it smoking and do a smalll sauce portion, it doesn't give the BIR effect. Jerry, CA and Haldi, to name a few, have massive burners, and still can't get the flavour their after. For the most part however, members with this gear do think it adds something positive.
Perhaps this is just one important piece of a large puzzle.
