Kohlrabi (Brassica oleracea var. gongylodes) is a cool-season annual cole crop that is related to broccoli, cabbage, cauliflower and Brussels sprouts. Kohlrabi originated in northern Europe in the 16th century. It forms a round globe just above the soil line with leaves emerging in a spiral from the stem. The edible portion is actually an enlarged stem, not root tissue. Kohlrabi can be eaten raw or cooked. In flavor, it is like a mild, sweet broccoli stem or turnip. Once the thick skin is peeled off, the crisp flesh can be eaten like a carrot often with a dip or in salads. It can be boiled, braised, used in soups and stews, made into home fries and even pies. In Kentucky, kohlrabi does well in the spring but is best as a fall crop.
