I think the tragedy is the mom not realizing that the mayo on the shelves today is for the most part only a distant relative of the “oil and egg yolk emulsion” she used to eat as a child.

That is, Millennials are justly rejecting a 100% chemical mix supposed to taste like a natural food, but whose ingredient list looks like a who’s who of food processing science, while it makes her fondly remember something that spoiled quickly if not eaten after opening. You can’t blame the young’uns for not having your memories.
