Seafood Cocktail Sauce 1 cup tomato catsup 1/3 cup lemon juice 1 tablespoon Worcestershire sauce 1 tablespoon grated onion 1 tablespoon grated green bell pepper Combine all ingredients, mix well, and allow to rest for at least 1 hour so the ingredients blend. Chill thoroughly before serving. Store in the refrigerator in a sterilized glass jar for up to 6 months. This sauce will not freeze well. For a spicier sauce, add 1 teaspoon Tabasco® sauce to the mixture before chilling. For an even spicier sauce, add 1 teaspoon horseradish along with the Tabasco® sauce.
