Oyster sauce is a rich, savory condiment widely used in Asian cuisine, especially Chinese cooking. Made from oyster extracts, soy sauce, sugar, and seasonings, it has a dark brown color with a glossy texture and delivers a balance of salty, slightly sweet, and umami flavors. Commonly used in stir-fries, marinades, and sauces, oyster sauce enhances the taste of meats, vegetables, and noodles, adding depth and a distinctive mouthwatering aroma to dishes.
