Fish sauce is the single, most important flavoring ingredient in Thai cooking (also well-loved in Laos, Cambodia, Vietnam, Burma and the Philippines). Used like salt in western cooking and soy sauce in Chinese cooking, good-quality fish sauce imparts a distinct aroma and flavor all its own. Large bottle will get you on the right track to start making all of your favorite Thai dishes. Simply put: if it doesn't have fish sauce, it can't be considered Thai.
