Fish sauce is a pungent, amber-colored liquid derived from fermented fish and salt, primarily used as a seasoning and condiment in various Asian cuisines. The highly fragrant sauce is commonly associated with Thai, Vietnamese, Filipino, and Indonesian dishes and imparts a savory, umami-rich flavor profile. Fish sauce variations exist across culinary cultures, but anchovies are commonly used as the key ingredient, contributing to its robust, salty taste.
Home cooks and consumers typically use fish sauce in small quantities, as its strong aroma is potent and can be overpowering. It is a versatile ingredient that enhances the flavors of soups, salad dressings, marinades, stir-fries, and dipping sauces. For those with dietary restrictions, a plant-based alternative made from soy sauce or liquid aminos, and seaweed can be developed to simulate similar umami characteristics.
