Nutrition and Health

The name kohlrabi comes from German and means “cabbage turnip.” Kohlrabi is a member of the brassica family, which includes cabbage, Brussels sprouts and kale. It has a subtle flavor reminiscent of other root vegetables such as turnips or potatoes and grows well in 91Ƶ gardens. The edible part is crisp and juicy and may be white, purple or green. It can be eaten raw or cooked. Kohlrabi is low in calories, contains no fat and is a good source of fiber, potassium and vitamins B6 and C.

Selection

Choose kohlrabi bulbs that are small and tender, when available, with bulbs 2 to 3 inches in diameter. Larger bulbs tend to be tough and woody but are more palatable when peeled.

Storage

Cut off leaves, wrap them in a damp paper towel and place in a plastic bag. Leaves can be refrigerated for three to four days. Kohlrabi bulbs can be stored for two to three weeks in the refrigerator.

Preparation

Wash kohlrabi just before using. Young kohlrabi bulbs are generally tender and do not require peeling. Larger bulbs should be peeled to remove the tough outer skin. Kohlrabi can be sliced, cut into quarters, cubed or julienned and eaten raw or steamed until crisp-tender or added to soups. It can be sautéed in olive oil or boiled and mashed. The crisp flesh can be served raw in salads, as a relish or as a crunchy accompaniment to dips. Prepare kohlrabi leaves as you would turnip greens or kale; they are excellent in salads or stir-fried.
