                                By its very nature, vegetarian oyster sauce is specifically formulated to be free of fish or any other seafood ingredients. This popular Asian condiment replaces the traditional oyster extract with plant-based alternatives, primarily mushrooms, to achieve its rich, umami flavor. However, those with severe allergies must be aware of potential cross-contamination.
