Peanut butter sandwiches were once considered food for the wealthy!

The peanut butter and jelly sandwich or PB&J is a sandwich, popular in North America, that includes a layer of peanut butter and either jelly or jam on bread, commonly between two slices, but sometimes eaten open-faced or with one slice folded over.

A 2002 survey showed the average American will have eaten 2,500 of these sandwiches before graduating from high school.

In the early 1900s, peanut butter was considered a delicacy that was only served in New York City's finest tearooms. The product was first paired with a diverse set of foods such as pimento, nasturtium, cheese, celery, watercress, and on toasted crackers.

In a Good Housekeeping article published in May 1896, a recipe "urged homemakers to use a meat grinder to make peanut butter and spread the result on bread." In June of that same year, the culinary magazine Table Talk published a "peanut butter sandwich recipe."

In 2013 we get to eat as many of these delicacies as we want!
