Peanut butter
Peanut butter was originally paired with a diverse set of savory foods, such as pimento, cheese, celery, watercress, saltines and 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." The following month, the culinary magazine "Table Talk" published a "peanut butter sandwich" recipe. An early recipe for a peanut butter and jelly sandwich appeared in the "Boston Cooking School Magazine" in 1901; it called for "three very thin layers of bread and two of filling, one of peanut paste, whatever brand you prefer, and currant or crabapple jelly for the other", and called it as "so far as I know original". In the early 1900s, this sandwich was adopted down the class structure as the price of peanut butter dropped. It became popular with children with the advent of sliced bread in the 1920s, which allowed them to make their own sandwiches easily.
