Oyster Sauce is used in a few Chinese-Thai dishes. There’s a rumor going around that it’s not actually made from oysters. Yes people, it’s made from real oysters, among other ingredients. Vegetarians will be happy to know that most Asian groceries carry a Veggie version. Usually it’s called ‘Mushroom Stir Fry Sauce’, ‘Mushroom Oyster Sauce’, ‘Vegetarian Oyster Sauce’ or the like. Do not confused this with ‘Mushroom Soy Sauce’, as that is just white soy sauce with mushroom flavoring. Store this in the fridge, as it goes bad.
