"I just watched the tailgate party episode that featured this recipe, and I was appalled at the incorrect information that Rachel provided. She states that she is modifying the traditional mayonnaise-based potato salad recipe to eliminate the need for refrigeration. First, today's store-bought mayonnaise is very different from the homemade mayonnaise from earlier times. It does not spoil quickly at room temperature because the eggs have been pasteurized. Second, she tops the salad with chopped hard-cooked eggs which are very perishable. Rachel would have done better to use mayonnaise from a jar and omit the eggs if she is truly worried about the safety of the food served at a tailgate party.
