Also called Chinese white cabbage, pak choy, pak choi and white mustard cabbage, bok choy is a mild, versatile vegetable with wide white thick curved stalks and broad deep green leaves with white veins. Baby bok choy is about seven inches long. Baby stalks are tinged with apple green, leaves are oblong, and deep green with smooth edges. Choose bunches with firm white stalks topped with crisp green leaves. Bok choy is available year-round in most supermarkets. It can be used in salads, as a cooked vegetable, or my favorite, stir fried. Bok Choy is related but not the same as Chinese Cabbage.
