You never forget your first quince. I first saw this strange fruit while driving through rice paddies on the western outskirts of Matsumoto, in mountainous central Japan. The trees themselves were small and scraggly, their knotted branches laden with the golden, apple-like fruit. Though tempted to jump out of the car and gather a few, I continued on, only to discover that quinces were practically impossible to find at Japanese markets. Even here in New York, quinces are remarkably difficult to come by, appearing only sporadically in the autumn. Yet as any quince aficionado knows, finding the fruit is only the beginning, for they take as much perseverance to procure as to prepare.
