Mash-Ups, Fast-Food Style

What happens when the country's fast-food behemoths pair off with a favorite brand-name food? Well, the best analogy we can come up with is that it tastes something like listening to two of your favorite songs perfectly mashed up together in the most mind-blowing, earth-shattering remix of all time.

Only a genius, for instance, could think to create an ice cream made out of Oreo crème filling — not the cookie, just the pure white goodness that according to a poll, 50 percent of eaters go to before dealing with its chocolaty surroundings. Or what about a Taco Bell taco with a shell made out of Nacho Cheese Doritos? Sounds pretty loco to us.

Fortunately, some of these food trysts have blossomed into full-on iconic food partnerships on which America depends. Where would 7-Eleven be without the Coke Slurpee (or the Mountain Dew, Fanta, Pepsi, Barq's, or Dr Pepper versions, for that matter) to cool customers off on a summer day?

But, alas, not all couples are meant to last. Sadly, some of these mash-ups were mere limited-time offers, like the Nutter Butter ice cream featured at Cold Stone Creamery. Needless to say, we're glad they gave it a go — even if it turned out just to be a fling.
