Tart sauce is a tangy condiment commonly used as a dip for fried seafood, particularly fish and shrimp. It typically consists of a base of mayonnaise mixed with ingredients like pickles, capers, and lemon juice, giving it a distinctive flavor that balances sweetness and acidity. This sauce is often served in restaurants alongside dishes like fish and chips or crab cakes. Its creamy texture and zesty taste enhance the overall dining experience, making it a popular choice for seafood lovers. Tart sauce can also be made at home, allowing for customization based on personal preferences.
