a study on pbj's.
I stumbled onto a site called Serious Eats. I searched "peanut butter" of course, and found a study on the peanut butter & jelly sandwich. One of the most satisfying treats, a bite of salty & crunchy (i prefer the kroger brand crunchy natural), a bite of sweet & tangy (my favorite jam being blackberry) all between two slices of wheaty bread that is as soft as a down pillow (i love my P.B.J in between 2 slices of Rudi's organic bread, multigrain oat being the closest to white bread without actually having white flour).
So serious eats had this study, a bread to pb to jam ratio.
Here is the diagram and ratio. 1 : 0.6 : 0.3 : 1 
ratio of bread-to peanut butter-to jam-to bread.
Just ask my friend Adree, I make the best damn peanut butter sandwich ever. She once asked me to make her a pbj because I always put so much peanut butter on it and it tasted divine.
If you are unsure, really, how to make a pbj, here are instructions and let's not forget the pictures too.
