I have eaten a lot of peanut butter sandwiches in my life, but never with jelly. That combination still strikes me as ungodly—kind of like turkey gravy over chocolate cake.
I agree. I disliked grape jelly intensely, and no other jelly tasted right, either except for apricot or peach jam. But I love PB and banana slices on wheat bread, PB on buttered white toast, PB on stoned wheat crackers or PB in the hollow of celery sticks.
Slices of apple, banana, sweet pickles or jelly all go great with peanut butter on a sandwich!
