I work in the food industry...a couple weeks ago I had a Chef tell me that, "Bacon is the Duct Tape of the kitchen. Anytime I eff something up, or more usually one of my cooks fucks something up, I just add bacon to it and everybody loves it."
Bacon is clearly superior to PB, though PB is high on the versatility chain.
I also find Cinnamon to be quite the versatile ingredient...I used to make a burger that had onions that I simmered in red wine & cinnamon for about 30 minutes blended into the beef...I really need to make me a batch of them soon.
