Oyster Sauce

Oyster sauce is a glossy, dark brown, viscous condiment with a molasses-like sheen. It tastes deeply savory with briny, caramelized sweetness and rich umami; it clings well in hot pans and quickly rounds out stir-fries, glazes, and pan sauces. Because it is derived from oysters, it is not vegetarian; common retail forms are bottled sauces labeled regular or oyster-flavored.\n\nDeveloped in Guangdong, China, it became a cornerstone of Cantonese cooking and spread widely through Chinese diaspora and Southeast Asian cuisines such as Thai and Vietnamese. Traditional methods reduce oysters to a thick extract, while modern production often fortifies with soy, sugar, starches, and flavor enhancers for consistency.
