Fish sauce is a pungent, savory condiment made from fermented fish and salt, commonly used in Southeast Asian cuisines such as Thai, Vietnamese, and Filipino cooking. It has a rich umami flavor with a salty, slightly funky aroma, and a thin, liquid consistency that adds depth to dishes. Typically, it is used to enhance the flavor of soups, stir-fries, and dipping sauces, providing a complex taste that balances sweetness and acidity. Historically, fish sauce has been a staple in coastal communities for centuries, prized for its preservative qualities and its role in traditional culinary practices.
