I was thinking you meant a legit frozen brick......Yeah, I've slushed Vodka before but I also think, and I'll repreat, think, it has a lot to do with the brand........I had several liquors up there and the only ones that slushed were the Smirnoff, the E&J (I know, I'm very ashamed) and the Goose. The Seagrams Gin, Cuervo and Jack didn't.
