I tried it, and failed.
I can't blame Pinterest, really. I stuck the rinds in there and forgot about them, for longer than 2 weeks, I'm sure! Then my daughter was sick for about a week, then I was sick for two weeks, and...the vinegar got quite scuzzy.
I dumped the contents outside, and I must admit that the vinegar didn't smell bad. But it didn't look like something I wanted to clean with either. Maybe next time I try this I'll keep the pickling time to the recommended two weeks. ;-)
