peanut butter and jelly sandwich

A peanut butter and jelly sandwich (PB&J) consists of peanut butter and fruit preserves—jelly—spread on bread. The sandwich may be open-faced, made of a single slice of bread folded over, or made using two slices of bread. The sandwich is popular in the United States, especially among children; a 2002 survey showed the average American will eat 1,500 peanut butter and jelly sandwiches before graduating from high school. There are many variations of the sandwich, starting with the basic peanut butter sandwich or jam sandwich. Preparation In basic preparation methods, a layer of peanut butter is spread on one slice of bread and a layer of fruit preserves is spread on another before the two sides are sandwiched together. (Jelly is a fruit-based spread, made primarily from fruit juice boiled with a gelling agent and allowed to set, while jam contains crushed fruit and fruit pulp, heated with water and sugar and cooled until it sets with the aid of natural or added pectin.) The water inherent to preserves can make the bread soggy, especially when the sandwich is prepared ahead of time as part of a bag lunch. To prevent this, the peanut butter can be spread first on both slices of bread. The fat in peanut butter will block the moisture from the preserves from entering the slices of bread. However, the preserves are now more mobile and can squirt out the sides. If the open sides are sealed, the preserves are thoroughly contained; this technique is utilized by the major manufacturers of sealed crustless sandwiches. Variations There are many variations on the sandwich; for example, honey or sliced fruit can be substituted for the jelly component, e.g., a peanut butter and banana sandwich.
