Add the Miracle Whip to the yolk. Food science lesson #4: Why should I use Miracle Whip instead of Mayonnaise? One main reason is, mayonnaise is made with raw eggs, and if it sits out too long, nasty things like salmonella poisoning can develop. If you are willing to keep your deviled eggs on ice all the time that they are not in the refrigerator, then you may use mayonnaise. Miracle Whip, on the other hand has been through a cooking process in it manufacture, therefore there is less of a chance of food poisoning with its use. Plus I just like the taste of Miracle Whip.
