Perhaps you've noticed the Cara Cara orange has graced our monthly changing List on the right right side of this page, but that little line doesn't do this citrus justice. This strain of navel orange originated at the Hacienda de Cara Cara in Valencia, Venezuela in 1976 and has been a cult favorite since. Also called pink navels for the blushed color of their flesh, Caras have a mellow acidity and sweet, almost floral flavor. They're in season rightthisveryminute, solid for 99 cents each at Whole Foods. Yesterday we tossed some segments with fennel, avocado, red onion, olive oil and a spritz of rose water (to pick up the orange's flowery notes) for a bright, summery salad alongside pan-roasted pork chops, but Caras are also perfectly delicious eaten out of hand. Get 'em while the last.
