If you really want to know how to make your Thai dishes taste authentic, you need to spend some time learning to do some of our common table condiments and sauces. This type of dipping sauce goes by the generic name "seafood sauce", or nam jim see fuut in Thai, and the name itself can refer to many different kinds of dipping sauce made a lot of different ways. In Thailand we eat a lot of fish and seafood, and we always serve them with a nice sauce that has a balance of sweet, salty, spicy, and sour flavors. This is what makes an ordinary steamed or fried fish taste like Thai food. Loaded with lots of fresh garlic and cilantro, this sauce is not cooked, so it only lasts a little while before it starts to lose some of it's sparkle. You should plan on making it up right before you serve the meal.
