Authentic Thai Recipe Ingredient: Oyster Sauce
น้ำมันหอย (Nam man hoi)
Oyster sauce describes a number of sauces made by cooking oysters. The most common in modern use is a viscous dark brown condiment made from sugar, salt and water thickened with cornstarch, flavored with a little oyster essence or extract, and some versions may be darkened with caramel, though high quality oyster sauce is naturally dark. It is commonly used in Cantonese, Thai, Vietnamese and Khmer cuisine.
