This reminds me of when I was a kid. There was a roller skating rink that made pickle flavored slushies. I don't know why, but every time I went there all the kids were going nuts over them. It was basically pickle juice and crushed ice.
I figured it out one day that the owner wanted to use the pickle juice some how and came up with this horrible concoction. I had one once and almost wretched. I was exiled for my lack of appreciation for the slushie.
