If they weren't already in your stocking this Christmas, add kumquats to your New Year's food list next to black-eyed peas. Welcome the first fruit of the next decade. These Southeast Asian imports adapt well to harsh southern winters, particularly in the citrus capitals of Florida and Louisiana, and are typically harvested from late fall into New Orleans' "winter months." It adapts well to urban environs, and its trees are small enough for backyard gardens or even patio pots. Look for the sweet, eat-it-off-the-vine Meiwa variety or the tart Nagami (better suited for canning or preserves). Get them at the Crescent City Farmers Market from organic suppliers L'Hoste Family Farm of Braithwaite.
