The ingredients in Red Lobster's tartar sauce include Miracle Whip, sweet pickle relish, confectioner's sugar, white onions and carrots. The sauce also includes sour cream and finely ground table salt.
To begin making Red Lobster's tartar sauce, chop a white onion in the food processor. Place three tablespoons of the chopped onion in a bowl, clean the food processor, and set the rest aside. Use the food processor to chop a carrot and add three teaspoons of the chopped carrot to the onion.
Combine 1/3 cup of Miracle Whip, two tablespoons of sweet pickle relish and 2/3 cup of sour cream in a mixing bowl. Add 1/4 cup of confectioner's sugar and 1/4 teaspoon of finely ground table salt and whisk until incorporated. Mix in the carrot and onion. Cover and refrigerate for two hours before serving. Tartar sauce usually accompanies seafood but also goes well with meats or bruschetta.
