Wok-Tossed Beef with Kohlrabi

KOHLRABI MEANS ‘CABBAGE TURNIP’; IT IS IN THE SAME FAMILY AS THE CABBAGE AND BROCCOLI, ITS TEXTURE AS CRISP AS ITS COUSINS. THERE ARE TWO TYPES OF KOHLRABI – PURPLE AND LIGHT GREEN – BUT GO FOR THE GREEN ONES, AS THEY DON’T SEEM TO BE AS TOUGH IN TEXTURE. WHEN BUYING IT AT THE MARKET, LOOK FOR A VEGETABLE THAT RESEMBLES A ROUND SPUTNIK SATELLITE.
