What is Seafood Sauce?
Seafood sauce, also known as cocktail sauce, is a tangy and spicy blend of tomato ketchup, horseradish, Worcestershire sauce, lemon juice, and hot sauce.
Horseradish is what gives cocktail sauce its distinctive flavor. It's a root vegetable with a strong smell and sharp, bold taste.
For the freshest taste, look for refrigerated horseradish on the top shelf of the grocery store's refrigerator. Shelf-stable options are also available in the condiments aisle.
Horseradish is in a glass jar and labeled as prepared horseradish, made by brands like Gold’s, or Silver Spring. Look for it in the refrigerator section at Publix here in South Florida.
Ingredients
- Ketchup: Many store-bought cocktail sauces are loaded with high fructose corn syrup so choose your ketchup wisely.
- Prepared Horseradish: Squeeze out any excess liquid before adding it to your sauce for the right consistency.
- Worcestershire Sauce
- Lemon Juice
- Hot Sauce: Adjust the amount to control the heat—more for spicier sauce, less for mild.
