This fruit of ancient lineage has been grown in China for over 4,000 years. It now thrives in most temperate climates, with California producing about 90 percent of the American crop. A relative of the peach, the apricot is smaller and has a smooth, oval pit that falls out easily when the fruit is halved. Throughout the world there are many varieties of apricot, including Riland, Tilton, Blenheim, Royal and Chinese. In color, the skin can range anywhere from pale yellow to deep burnt orange; the flesh from a golden cream color to brilliant orange. Because they're highly perishable and seasonal, 90 percent of the fresh apricots are marketed in June and July. When buying apricots, select plump, reasonably firm fruit with a uniform color. Store in a plastic bag in the refrigerator for up to 3 to 5 days. Depending on size, there are 8 to 12 apricots per pound. Dried apricots are pitted, unpeeled apricot halves that have had a large percentage of the moisture removed. They're usually treated with sulfur dioxide to preserve their color. In addition to being rich in vitamin A, dried apricots are a valuable source of iron and calcium. The kernels of the apricot pits are used in confections and to flavor liqueurs. Like bitter almonds, apricot kernels are poisonous until roasted.
