Americans spoon it out of the jar, eat it in sandwiches by itself or with its bread-fellow jelly, and devour it with foods ranging from celery and raisins (“ants on a log”) to a grilled sandwich with bacon and bananas (the classic “Elvis”). Peanut butter is used to flavor candy, ice cream, cookies, cereal, and other foods. It is a deeply ingrained staple of American childhood. Along with cheeseburgers, fried chicken, chocolate chip cookies (and apple pie), peanut butter is a consummate comfort food.
