Mayonnaise is an emulsion of egg yolks, oil, acids and seasonings; Miracle Whip, on the other hand, is made with water, high fructose corn syrup, and soybean oil, giving it a sweeter flavor, as opposed to the tangier taste of mayo. Miracle Whip also contains a unique blend of spices that include mustard, paprika, and garlic, adding to the taste difference.
