What is the origin of the Chinese wok?
The Chinese wok has a long and storied history that dates back to the Han Dynasty (206 BCE – 220 CE). The word “wok” is derived from the Cantonese term “wok,” which means “cooking pot.” The wok was originally made from cast iron or carbon steel and was used for stir-frying, braising, and steaming a variety of dishes.
Over time, the design of the wok has evolved to include a round bottom, which allows for efficient heat distribution and easy stirring. The wok has become an essential tool in Chinese cuisine, and its popularity has spread to other parts of the world. Today, woks are made from a variety of materials, including stainless steel, non-stick coatings, and ceramic.
