Oyster sauce

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 oyster extracts, sugar, salt and water, thickened with corn starch (though original oyster sauce reduced the unrefined sugar through heating, resulting in a naturally thick sauce due to caramelization, not the addition of corn starch). Today, some commercial versions are darkened with caramel, though high-quality oyster sauce is naturally dark. It is commonly used in Chinese, Thai, Indonesian, Malay, Vietnamese, and Khmer cuisine.
