What is Yi Fan?
Yi fan refers to the traditional Chinese cooking technique of “one wok, one recipe.” It involves using a single wok to prepare an entire dish from start to finish.
Yi fan originated from traditional Chinese cooking methods that valued single-purpose cookware. Using one wok allows the flavors to blend and build in layers.
The yi fan technique boosts umami flavor as the ingredients combine with the wok seasoning. It also allows personalized seasoning and texture.
While yi fan was historically used out of necessity, it is now valued for enhancing the dining experience in modern Chinese cooking.
A seasoned carbon steel wok evenly distributes heat. A spatula stir-fries and scoops. A ladle adds liquid. Bamboo brushes clean.
Who Uses the Yi Fan Technique?
Yi fan is used by:
- Home cooks who want authentic flavor for Chinese cuisine
- Professional chefs at Chinese restaurants seeking high quality
- Street food vendors doing high volume stir-fries
- Culinary students learning traditional Chinese cooking
- Cookbook authors developing authentic Chinese recipes

Mastering yi fan takes time but yields rewarding results in flavor. Patience and the right equipment are key.
