What is Oyster Sauce?
Oyster sauce is a savory condiment commonly used in Asian cuisine. It is made by simmering oysters in water until the liquid caramelizes into a thick, brown sauce. The sauce is then flavored with salt, sugar, and sometimes soy sauce. The result is a rich, umami-packed ingredient that enhances the flavor of various dishes.
