Asian Pears. Janick and J. Simon eds. Timber Press, Portland, Oregon. Asian pears comprise a large group of pears that are crisp in texture and, when mature, are good to eat as soon as harvested or for several months after picking if held in cold storage. This ready-to-eat feature may make them more acceptable to some people than European pears that are usually served when soft and juicy, which takes about a week to occur after removal from cold storage.
