This delicious sauce is the key to authentic Chinese flavor. Used in the most popular Chinese foods — classics like stir-fried beef with broccoli, chicken and vegetables or drizzled over steamed greens — oyster sauce is a key ingredient in many Asian recipes. It's made by condensing the extracted liquor from fresh oysters and combining it with Kikkoman soy sauce and a touch of brown sugar. Produced to the highest-quality standards, Kikkoman Oyster Sauce produces the same great taste every time you use it.
