Forgot to mention that I also brought home another jar of pickles, and two more colors of kool-aid (berry blue and grape), but upon closer inspection I seem to have grabbed the wrong jar. All of the pickles in this jar are of the "mini-gherkin" variety and very dark, so I don't think they'll take as well.
Edit: fuck it
in the fridge they go.
I think the blue will take really well. I don't know about the grape. It's very dark and sinister-looking and has scuzzies on the top that don't stir away.
