In Guangdong, oysters are called "hao," and oyster sauce is a seasoning made by simmering oysters. As a traditional umami condiment widely used in Guangdong cuisine, it ranks among the most popular sauce products. Crafted from oysters—often dubbed "milk of the sea"—it is produced by boiling the oysters, extracting their juices, concentrating the liquid, and refining it with additional ingredients.Oyster sauce boasts a savory flavor, rich oyster aroma, moderate viscosity, and high nutritional value. It serves as a key ingredient in traditional Cantonese dishes such as oyster sauce beef with mushrooms, oyster sauce greens, and oyster sauce noodles.
Historical Origins Oysters, marine mollusks prized for their delicious meat and rich nutrition, are widely distributed along China's southern coast.In 1888, a small family workshop quietly opened in Nanshui Village, Zhuhai, Guangdong Province, specializing in a novel condiment—oyster sauce.
The workshop's owner, Li Jinshang, born in 1868, hailed from Yongli Village, Qibao Town, Xinhui, Guangdong. Orphaned at a young age, he and his mother, Cai, relied on farming for survival.After standing up to local bullies and landlords, he faced persecution and fled his hometown. He eventually settled in Nanshui, Zhuhai—a small island in the Pearl River Estuary renowned for its oyster production. To make ends meet, Li opened a small teahouse where he cooked and sold oysters.
One day, while preparing oysters as usual, Li Jinchang stepped away to attend to other tasks and forgot to tend the fire. After a long while, an intense aroma wafted through the air. Rushing back, he thought, "Oh no, they must be burnt!"Lifting the lid, he discovered a thick, dark brown, viscous liquid settled at the bottom of the pot. Its rich aroma was irresistible. He casually scooped a bit into his mouth and tasted it, finding it incredibly delicious.
Thus, quite by accident, a new condiment—oyster sauce—was invented! Truly, "unintended efforts yield unexpected results," and "it came without any effort." Seizing this fortunate opportunity, Lee Kum Sheung had a flash of inspiration. He began boiling down this novel condiment specifically for sale, formally establishing Lee Kum Kee Oyster Sauce Factory in 1888.

Called "hao" in Guangdong and "li" in Fujian, they are termed "lihuang" in Zhejiang and "haizizi" in northern regions. Their flesh is deliciously fresh and nutritionally rich.They can be eaten fresh, dried to make dried oysters, or processed into canned goods, oyster sauce, oyster powder, and more. They are produced along China's northern coast and in Guangdong, both through aquaculture and natural growth.Northern varieties are smaller, while Guangdong oysters are larger. The production season typically runs from December to around March. Many mistakenly believe oyster sauce is an oil, but like soy sauce, it is not an oil but a seasoning.
Oyster sauce is made by simmering dried oysters (oyster sauce paste), then filtering and concentrating the broth.It is a nutrient-rich, savory condiment. The production process involves multiple steps, with the most critical being simmering fresh oysters in water until they reach the desired viscosity—the most time-consuming stage.
