Kool-Aid Pickles. We've made this recipe with the following flavors of Kool-Aid: Black Cherry (excellent balance of sweet & tart) and Watermelon Cherry (wasn't enough Kool-Aid flavor in this one for us). We have a Grape batch in the fridge right now and are anxiously awaiting them. Fun thing to do especially if you have kids...or not. :) EDIT: Grape was not well-received (not yummy at all!) in our house. Little #2 picked pink lemonade for the latest batch so we'll see.
