This iconic sandwich is known for being sweet and salty, inexpensive, and easy to make. Its versatility has allowed it to endure, even when peanut allergies led to school bans, as alternative nut butters and seed butters became substitutes.

The PB&J concept has also been adapted in various eateries, from delis to high-end restaurants, offering creative takes on the classic sandwich. Further details about the history and variations of the PB&J are available.
