@StinkyTracy Miracle whip isn't mayonnaise. It's dressing and has a few dozen more ingredients than mayo.
dressing.
In 1933 Inventor Charles Chapman's patented emulsifying machine allowed regular mayonnaise to be evenly blended with cheaper dressings and more than 20 different spices (plus sugar). The result was Miracle Whip, which debuted at the 1933 Chicago World's Fair. Promising to create "Salad Miracles with Miracle Whip Salad Dressing," the Whip was an instant hit (Note: It's not known if the dressing is responsible for any non-salad-related miracles.)
The main difference between Miracle Whip and mayonnaise are the sweeteners: high-fructose corn syrup and sugar are the fourth and fifth ingredients, respectively, of Miracle Whip.
