Tip: Fish sauce is a pungent Southeast Asian condiment made from salted, fermented fish. Find it in the Asian-food section of well-stocked supermarkets and at Asian specialty markets. We use Thai Kitchen fish sauce, lower in sodium than other brands (1,190 mg per tablespoon), in our recipe testing and nutritional analyses.
