What It Is
Fish sauce is a salty, tangy condiment made from fish. In fact, the best fish sauces are made with just a few ingredients: anchovies, salt, water, and sometimes sugar. Despite its name, fish sauce doesn't taste strictly fishy -- it can give a rich and savory base of flavor to a range of dishes. It's popular throughout countries in Southeast Asia, such as Thailand, and often used in soups, salads, noodle dishes, and curries.
Buying and Storing
Find fish sauce in the international aisle of your supermarket or at Asian specialty markets. Store fish sauce in the refrigerator or pantry (check your label). It will keep indefinitely.
How to Use It
Fish sauce can be used much like soy sauce, and a few dashes go a long way. A spoonful will add depth to stir-fries or soups. Add it to marinades for meat or fish, or use it to make dipping sauces and salad dressings.
