"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.
"The main thing we look at with this dynamic in our work is the 'Why?' Why do people love this stuff so much?" Thobe said. "And I think it's that salty-sweet, hot-cold dynamic that works so well. It's activating so many of our senses. It's taste, it's texture -- it confuses your taste buds… in a good way. It's a crazy, intense experience."
"When you look at how chefs develop their meals, they want to strike balance of flavors, and make sure everything play well together. This is an encapsulation of that. The fries have to be crispy and hot, the Frosty has to be cold. The fries bring the savory and the Frosty brings the sweet. It's basic chemistry, really. It's how food works, and part of the reason why we love to eat."
