Fish sauce is an essential ingredient in my pantry. It has a nice salty-sweet flavor to it, and you use it very sparingly, like Anchovy paste. A little goes a long way! There are several brands of fish sauce, the best one I have found so far is called “Three Crabs”. Good fish sauce should be the color of brewed tea. Anything darker (like the color of soy sauce) is a lower quality brand. If you think that “fish sauce” sounds like a weird ingredient, guess what? If you enjoy Thai and Vietnamese dishes…most of them call for fish sauce in the ingredients! After opening, you can store fish sauce in your pantry or refrigerator.
