koolickles: history: Popular in small, predominantly African-American Mississippi Delta towns, Koolickes are simply dill pickles that have been allowed to soak in a strong mix of Kool-Aid and brine. Koolickles combine two flavors well; sour and sweet. Their popularity is soaring; the New York Times wrote a great article about these pickles, and they even received a nod from Alton Brown on his show, "Feasting on Asphalt".
