“This recipe is from the 1968 McDonald's Manager's Handbook put out in 1969 (1968 year) They quickly removed the recipe after realizing they had a very appealing "secret sauce." It was included as an emergency recipe in the event a particular store ran out of the pre-made sauce. Enjoy!”
1 cup

Ingredients Nutrition

  • 14 cup Miracle Whip
  • 14 cup mayonnaise
  • 2 12 tablespoons Wishbone Deluxe french salad dressing (the orange stuff)
  • 12 tablespoon Heinz® sweet relish
  • 1 tablespoon Vlasic dill pickle relish (Heinz dill relish also works)
  • 1 teaspoon granulated sugar
  • 1 teaspoon dried onion flakes
  • 1 teaspoon white vinegar
  • 1 teaspoon ketchup
  • 18 teaspoon salt


  1. Mix everything very well in a small container. (No streaks!)
  2. Microwave 25 seconds, and stir well again. Cover, and refrigerate at LEAST 1 hour before using (to allow all of the flavors to "meld").
  3. Makes about 1 cup -- enough for about 8 Big Macs!
