On April 2, enjoy the time-tested sandwich combo that has been around for nearly a century: peanut butter and jelly! When a recipe involving peanut butter was published in 1901, this delicious pair initially became well-known. Since then, both children and adults have come to associate it with lunchtime. So enjoy this time-tested delight with some bread, your preferred jelly, and creamy or crunchy peanut butter (or both!).
