The somewhat smaller than golf ball sized yellow-orange fruits taste a little bitter, and somewhere between a lemon and a grapefruit. Europeans have used it dried or candied, the American colonists used it for its pectin, and in China, from whence it hails, it has been used medicinally for at least a few thousand years.
