A commercial-sized 6 kg jug of Donggu Superior Oyster Sauce (东古上等蚝油). This thick, savory sauce delivers a rich umami profile. Product Details & Culinary Uses • Net Weight: 6 kg (indicated by "净含量: 6kg" at the bottom of the label). • Intended Uses: The label highlights its versatility for grilling/barbequeing (烧烤), quick stir-frying (小炒), dipping (蘸点), and marinating meats (腌制). • Target Audience: This heavy plastic jug format with an integrated handle is primarily packaged for commercial kitchen use, canteens, and restaurants. Storage Recommendations Because this is a large volume of a seafood-based condiment, follow these safety guidelines once opened: 1. Wipe the opening: Clean the cap and rim thoroughly after each use to prevent bacterial buildup. 2. Refrigerate: Keep the large container stored in a commercial refrigerator or cold storage unit to halt mold growth and extend its shelf life. 3. Decant safely: If using it daily, decant smaller portions into clean, dry squeeze bottles rather than opening the main jug repeatedly.
