Most of these crisp, juicy apples are imported from New Zealand and Australia, though the United States now produces some, principally in California and Arizona. The Granny Smith's freckled green skin covers a sweetly tart flesh that's excellent for both out-of-hand eating and cooking. The imported crop arrives during summer, while those from the United States are available through the winter months, making the popular Granny Smith a year-round, all-purpose apple. See also apple.
