But Wendy’s is currently giving vanilla Frosties a rest in favor of a summery new flavor that debuted in Canada last year: strawberry. As Thrillist reports, there’s a simple reason why vanilla, strawberry, and chocolate Frosties can’t all peacefully coexist: Frosty machines can only produce two separate flavors at a time. But when it comes to functionality, the Wendy’s Frosty machine has a much better track record than its seemingly always broken rival, the McDonald’s McFlurry machine.
