Here in the normal world we call "jelly", "jam". We call jelly what you all call jello. You can imagine the confusion this caused for many years. I've never understood the reverence with which pb&j is held by you yankee doodles. It's ok but the way you carry on, you'd think it was your national food. Which, given your obesity rates, it very well might be.
I actually prefer peanut butter and honey but I most prefer pb on it's own - preferably on toast or better yet, fruit toast!
