The prepared peanuts are ground in two stages to avoid generating too much heat, which can reduce flavor quality. The first stage reduces them to a chunky paste. The second stage incorporates additional ingredients—such as sugar and salt—and reduces the peanuts to the familiar, smooth peanut butter texture before final packaging.
Although both unopened and opened jars of Peter Pan Peanut Butter may be stored at room temperature, refrigeration may help retain the product’s optimum flavor—particularly in places where the room temperature tends to be warm. Keep in mind that colder storage temperatures will make Peter Pan Peanut Butter firmer and not as easy to spread. We do not recommend freezing peanut butter.
You may store both unopened and opened jars of Peter Pan Peanut Butter at room temperature. Exposure to air and excessive heat may accelerate the loss of optimum flavor and—in the case of heat exposure—cause oil separation. Avoid this by keeping the jar tightly closed and in a cool place. Cold temperatures, even those that still are above freezing, may change peanut butter’s consistency, texture, and thickness.
This varies slightly depending on the actual product. Creamy and Crunchy varieties of Peter Pan Peanut Butter have a recommended shelf life that is 18 months from the date of manufacture. Beyond this date, the product does not spoil, but may develop “off” flavors due to age. The end of the recommended shelf life is noted by the “Best By” date stamped on the jar.
Swift & Company introduced “E.K. Pond” peanut butter in 1920. In 1922, the company adopted a new process for a smoother, more stable peanut butter. In 1928, Swift renamed the product “Peter Pan.” Originally, Peter Pan Peanut Butter was packaged in a tin can opened by a turnkey that allowed the can to be re-covered by the lid. The package was changed to glass jars during World War II because of metal shortages. Later, lighter, unbreakable plastic jars replaced the glass ones. In 2021 Peter Pan introduced its new Almond Butter.
