Raisins
Sweet grapes that are allowed to dry and shrivel up are called raisins. Until medieval times, raisins were second behind honey as a top choice for sweeteners. Today, the majority of the world's supply of raisins comes from California and are either dried Thompson Seedless, muscadine, or Black Corinth (Zante) grapes. In 1873, California suffered a devastating drought that literally dried the grapes on the vine. Looking to recoup some of the grape crops, an enterprising marketer in San Francisco sold the dried and shriveled grapes as "Peruvian Delicacies," and the California raisin industry was off and running.
