Sour Patch Kids Oreos? Peeps Pepsi? What's behind the weird flavors popping up on store shelves

Surprising flavor combinations – think gravy-flavored Jones Soda or Sour Patch Kids Oreos -- are showing up more frequently in grocery stores and restaurants. Earlier this year, IHOP and Lay’s introduced Rooty Tooty Fresh ’N Fruity potato chips, which were designed to taste like strawberry-topped pancakes with a hint of bacon. Last summer, there were mustard-flavored Skittles. While it’s tempting to pass off these limited-time flavors as social media stunts, experts say there’s more to the story. Food companies are responding to the changing and expanding tastes of consumers while also trying to keep brands relevant and distinct to win space on crowded store shelves.
