In Creamy and Crunchy are the stories of Jif, Skippy, Peter Pan; the plight of black peanut farmers; the resurgence of natural or old-fashioned peanut butter; the reasons why Americans like peanut butter better than (almost) anyone else; the five ways that today's product is different from the original; the role of peanut butter in fighting Third World hunger; and the Salmonella outbreaks of 2007 and 2009, which threatened peanut butter's sacred place in the American cupboard.

To a surprising extent, the story of peanut butter is the story of twentieth-century America, and Jon Krampner writes its first popular history, rich with anecdotes and facts culled from interviews, research, travels in the peanut-growing regions of the South, personal stories, and recipes.
