Oyster Sauce Vs. Fish Sauce
It is fairly common to see people debate over the use of oyster sauce and fish sauce. Here is a brief overview about the differences between these two sauces.
As the names rightly suggest, oyster sauce is made from oysters and fish sauce is made from fish. Like the basic ingredients, the method of preparation too differ. Both the sauces are different in color, consistency, and flavor. However, they are substituted for each other in some recipes. It is always better to have a basic understanding about these sauces, if you plan to use them.
Differences Between Oyster Sauce and Fish Sauce
Method of Preparation
Oyster sauce is made from oysters, which are allowed to boil in water over low heat, till the juices reduce to form a thick sauce. Nowadays, most of the store-bought versions are made with sugar, salt and cornstarch. They contain a small amount of oyster sauce or oyster essence for flavor. You may also find vegan versions of oyster sauce prepared with shiitake or oyster mushrooms.
Fish sauce is prepared by fermenting fish along with salt. While anchovies are mainly used for making this sauce, other types of fish are also used for this purpose. Fermentation for a short period yields a sauce with a pronounced fishy flavor. The sauce will have a rich, nutty flavor, in case of longer fermentation. The longer the period of fermentation, the lesser the fishy smell. Usually, the period of fermentation ranges between one year to 18 months.
Color, Consistency
Oyster sauce is brownish, whereas fish sauce is reddish brown or amber-colored. You may also find some types of fish sauce that contain additives, like spices, garlic and green chilies. Oyster sauce is thick in consistency, whereas fish sauce is watery and clear.
Flavor, Odor
As it is prepared by reducing oyster extracts, oyster sauce is sweet, with a salty undertone. However, fish sauce has a prominent salty and nuttier flavor. It has a fishy smell too. This smell can be overcome by mixing it with a small amount of lime juice. Or else, you can use it in small amounts. As compared to the fish sauce, oyster sauce has a milder aroma. You can sample oyster sauce straight out of the bottle.

While oyster sauce is Chinese in origin, fish sauce has been used in various regions, through the centuries. Though fish sauce is said to have originated in Asia or Europe, the exact place of origin is still unknown. Oyster sauce is widely used in Chinese cuisine, especially in stir-fries.
