1/2 cup mayonnaise
2 tablespoons French dressing
4 teaspoons sweet pickle relish
1 tablespoon finely minced white onion
1 teaspoon white vinegar
1 teaspoon sugar
1/8 teaspoon salt

This tastes like the real thing, combine everything in a blender and whip to blend. This should be refrigerated for at least an hour for best flavor.

Makes about 3/4 cup.
