The consistency and size of kohlrabi is much like a turnip, except it tastes like a slightly spicy cabbage. Some varieties get huge, up to 10 lbs. Comes in green, red, white, and purple. They mature faster than cabbage or broccoli and can be planted much closer together.
Basically I slice them and dip them in ranch dressing, or eat with some good dark beer. Mom like them in stir fry. I like White Vienna myself. Gourmet seed has some good varieties:
