The Almighty P, B, and J sandwich

The famous P, B, and J sandwich is the most popular food item among humans. Scholars for centuries have debated what "PB&J" stands for, but it is not known for certain. 
Several variants of the PB&J exist, including the legendary Smuckers Uncrustables. Rumors have surfaced of a sequel to the PB&J being in the works, with the working title PB&J 2. 
Multiple children have reported allergic reactions to one of the three components of a PB&J, but researchers are still uncertain whether the reaction was to the P, the B, or the J.Category:Foods
