Have you ever eaten a kohlrabi? These little sputnik-shaped vegetables come in green or purple, can be eaten raw or cooked, and taste a lot like broccoli stems. The word kohlrabi is German for cabbage turnip (kohl as in cole-slaw, and rübe for turnip) though kohlrabi is more related to cabbage and cauliflower than to root vegetables. We usually eat them raw, just peeled, sliced and added to a salad, but they are also delicious cooked and are often used in Indian cuisine.
