While not exactly junk food, I thought I'd mention these for the novelty value.
Pronounced, "Grape-L", they're a patented process owned by Grapple Fruits, LLC of Wenatchee, WA.
They specifically use Washington Extra Fancy Fuji Apples, because they absorb the grape flavor best. They simply soak the apples in concentrated grape flavor and pure water. All ingredients are USDA and FDA approved and the process has been licensed by the Washington State Department of Agriculture.
The apple takes on no additional sugars or calories, and are not genetically altered in any way.
It's largely designed as a way to get kids to eat more apples, because apples just don't taste good enough I suppose. Grapples have been around for a couple of years now, but are only now making their way into grocery stores across the country.
