P.F. Chang's co-founder, Philip Chiang, explains that the wok line is the foundation for the company's innovative cooking method, which involves a dedicated team of cooks who specifically prepare food using this method. The key to the success of this method is the ability to achieve high temperatures and create layers of flavor through rapid tossing and heating of ingredients in a well-seasoned wok. The wok's structure, its bowl-like shape, allows it to disperse heat quickly and sear ingredients quickly, giving them tender-crisp textures. However, it is unlikely to replicate this method at home unless you have a commercial Chinese kitchen gas range.
