Susan Puckett's wonderful book Eat, Drink, Delta (UGA Press) is a great guide to the foodways of the Mississippi Delta area. From this source I learned about Kool-Aid Pickles or Koolickles. Convenience stores in the area sell the doctored jumbo dills in big jars near the checkout line. I was curious but dubious. All that food color couldn't completely dampen my curiosity, so I gave them a try. They are actually rather good, much to my surprise. I expected a chemical processed taste. If I closed my eyes, however, the fruit and acid brought to mind the chutneys I ate in India.
My pickle-loving boy took an adventure bite but didn't care for more.
