What it is

Fast cooking of small pieces in little oil over high heat in a round-bottomed vessel. The Qimin yaoshu (c. 544) contains the first written stir-fry recipes and set the course of Chinese cooking.

The cast-iron wok existed in Han times, but stir-frying as a common technique became widespread between the Song and Ming dynasties; the Qimin yaoshu is the first textual reference.

What it led to

  • Chinese cooking with high heat and fine cutting
  • fuel saving in kitchens with scarce wood
  • spread of the wok through Southeast Asia and the world
