While Thrillist hasn't had a chance to taste test the pickle-flavored treat yet, the folks at Food & Wine have, and they gave it a pretty positive review. Specifically, they described it as "surprisingly delicious" and as having more of a sweetness than a tang to it (so a big 'ol frozen pickle back shot it is not).
The drink's arrival comes in the midst of a pickle juice moment, if you will. The briny green dregs left from pickling has become somewhat of an "it" beverage as of late. It's been hailed as a legitimate Gatorade-replacement for athletes, been soda-fied, and now even Walmart is selling pickle-flavored ice pops.
It's tough to imagine that a pickle-flavored slushie is going to provide the same sort of refreshment for most diehard sweet-toothed Sonic fans, but then again, it could just be the perfect pairing with a burger and fries.
