A winter farmers market initially looks deserted, but it has plenty of unusual root vegetables and varieties of dark leafy greens. The apples and pears overflow their crates. Some markets, such as New York City, also serve goat cheese, yogurt, cured and cuts of meats, milk, honey, bread, eggs, grains, and dried beans. Heirloom carrots in purple and varieties of potatoes are visual reminders of whole food’s diversity.
