As director of culinary innovation, Thobe's job revolves around experimenting with what Wendy's does, and reinventing what fast food can be. The fry/Frosty combo could easily be something that came out of that lab. But Thobe assures that this innovation is and was 100% organic.
"I don't think it is anything my predecessors imagined," she said. "It's just one of those things that people have been doing since Dave Thomas invented the Frosty. It's an underground, magic pairing that took off on its own.”
The Frosty was one of the five original items on Wendy's menu (alongside hamburgers, chili, fries, and soda). Dave Thomas -- Wendy's founder -- developed the recipe himself. He loved thick shakes as a kid and wanted a shake so thick that it required a spoon… or fries.
