Passage One
Have you ever heard of a pawpaw(木瓜)？ If not, do not feel bad. Many Americans do not know of the fruit, although it is native to the U.S..Once, however, it was one of the most popular fruits in North America. Happily, those who love the pawpaw are trying to return it to its former position in American foods.
A pawpaw is a tropical fruit that used to be grown along the East Coast from New York to Florida and all over the eastern U.S..At one time, it could be found as far west as Nebraska.
The pawpaw was an important food for Native Americans and even early European settlers. Pawpaws reportedly were a favorite treat of George Washington, the first U.S. president, who especially liked them cold. Thomas Jefferson, the third U.S. president, was also s fan of the fruit. He planted papaws at his home in Virginia. He also sent pawpaw seeds to his friends in France, American explorers Lewis and Clark wrote in their journals about the pawpaw.
The pawpaw is difficult to be sold commercially. The fruit requires a very special environment---low, wet areas that sometimes flood. It has a very short harvest season, from two to three weeks in September and October. In addition, the fruit is good to eat for only two to three days after harvesting. This makes it hard to sell anywhere distant from the pawpaw tree it comes from.
Planters are again growing pawpaw trees and harvesting the fruit. In several states farmers have organized “pawpaw festivals” to reintroduce people to food. At such a festival in Maryland recently, farmers displayed different products made with pawpaws, like pawpaw jams, pies, ice-cream and beer.
