Actually the "ultimate peanut butter sandwich," with just enough "tooth" to feel good as well as taste right, and just enough "juice" to keep the PB from sticking to the roof of your mouth, is with those "bread and butter" pickle slices that grandma used to make.
Dill pickles add too much of their own flavor, - that clashes with the PB. The B&B pickles just blend and bring out the best of both.
