Nectarines have a smooth skin that is golden yellow with large blushes of red. Their yellow flesh has a noticeable pink tinge with a distinctly sweet aroma and pronounced flavor. There are more than 100 varieties of nectarines. Nectarines most likely originated in China more than 2,000 years ago and were cultivated in ancient Persia, Greece, and Rome. Later, they were introduced to America by the Spanish. Nectarines can be used and prepared in the same ways as peaches, with no need to peel because they have no fuzz. Leave the skins on when making pies, cobblers, and fresh fruit salads.
