Gretchen McKay | Pittsburgh Post-Gazette (TNS) PITTSBURGH — In the mood for a quick and easy dessert that ushers summer sweetly into fall? The end of August and beginning of September are typically when peaches shine the brightest at Pennsylvania farmers markets and in local groceries. Georgia may call itself “The Peach State,” but Pennsylvania grows a lot of the fruit, too — nearly 40 million pounds each year with an annual value of approximately $20 million. Some of the most celebrated fruit wear a “Chambersburg” sticker.
