1. A Brief History of Oyster Sauce

The story of oyster sauce begins in Guangdong, China, in the late 19th century. According to legend, a man named Lee Kum Sheung accidentally overcooked a pot of oyster soup while running a food stall. Instead of discarding the thick, dark reduction, he tasted it—and discovered a richly flavored sauce that was salty, sweet, and bursting with umami. He began selling it, and it quickly became a staple.

Lee Kum Sheung would go on to found the Lee Kum Kee brand, now one of the most recognizable names in Asian sauces worldwide. What began as an accident became an essential part of Chinese cooking, and oyster sauce has since become indispensable in both professional kitchens and home pantries.
