The name kohlrabi comes from the German kohl, meaning cabbage, and rabi, or turnip.
The taste and texture of kohlrabi are similar to those of a broccoli stem or cabbage heart, but milder and sweeter, with a higher ratio of flesh to skin. The young stem in particular can be as crisp and juicy as an apple, although much less sweet.
Handling: If the kohlrabi leaves are still attached to the bulb, trim them and store separately. If the leaves are in good shape—firm and green—they can be cooked but will need to be used within a couple of days.
Bulbs should be stored, unwashed, in a plastic bag. They will hold for about a week in the refrigerator. Smaller kohlrabi are the sweetest and most tender.
Tender, young kohlrabi is delicious eaten raw. Peel the outer skin with a paring knife. Slice, dice, or grate, and add to salads. Use on raw vegetable platters or serve with a creamy dip. Substitute in recipes calling for radishes. Grated kohlrabi can be added to slaw, but lightly salt it first and let stand for several minutes. Squeeze to remove any excess water before adding dressing. Kohlrabi can also be steamed or boiled. For this preparation don’t peel until after they are cooked. Steam or boil until bulbs are tender, peel skin, and season with butter, salt, and pepper, a cheese sauce, or just enjoy plain.
