Oyster Sauce

This thick brown sauce is made from a concentrate of oysters cooked in soy sauce and brine. Despite its name, oyster sauce does not taste fishy. It has a rich flavour and is used not only in cooking but also as a condiment, diluted with a little oil, for vegetables, poultry and meat.

It is usually sold in bottles and can be obtained from Chinese or Asian grocers and supermarkets. I find it keeps best in the refrigerator. There is a version available for vegetarians, which is made with ... just mushrooms.
