Dehydrated apples. Grown in temperate zones throughout the world and cultivated for at least 3,000 years, apple varieties now number well into the thousands. Apples range in color from lemony yellow to bright yellow-green to crimson red. Their textures range from tender to crisp, their flavors from sweet to tart and from simple to complex. They're available year-round but are at their best from September through November when newly harvested. Apples are a good source of vitamins A and C.
