What You Should Know About Kohlrabi
Kohlrabi belongs to the cabbage family, although it doesn’t look much like its vegetable cousins. In contrast to other types of cabbage, kohlrabi does not develop from the leaves or flowers of the plant, but from a thickening of the plant stem above ground. Kohlrabi is a cross between a wild cabbage and a wild turnip. Most kohlrabi is light green in color, although purple kohlrabi has become increasingly popular in recent years.
The exact origin of kohlrabi is still disputed today, however it is know that the vegetable was already being widely consumed in ancient Rome, where it was know as "caulo rapa".
Although kohlrabi is available all year round, it tastes best during its peak season from April/May through late summer.
Kohlrabi is slightly sweet and mild, with a slight cabbage-y taste.

Shopping and Cooking Tips
If possible, buy kohlrabi with the leaves still attached. In addition to their health benefits, kohlrabi leaves are a great indicator of the vegetable’s freshness. If the leaves are green and crunchy, the quality of the kohlrabi itself is usually up to par. The outer skin of the root should also look undamaged and smooth. As a rule of thumb, the smaller the kohlrabi, the more tender it tastes - very large roots can often have a wood-like flavor.
Fresh kohlrabi can stay fresh in the refrigerator for about 1 week. It’s better to separate the leaves when storing, removing them from the root and keeping them in a plastic bag before preparing them.
Wash the kohlrabi thoroughly, cut off the leaves and peel the root. Cut the lower end with a sharp knife, removing any woody, fibrous parts.
What To Make With Kohlrabi
The light green kohlrabi leaves taste great and are full of nutrients - far too good to throw away! Therefore, only remove large leaves that are no longer quite crisp and fresh and prepare the rest this way: wash them thoroughly, shake dry, then chop them very finely and sprinkle over the kohlrabi or other vegetables, or vegetable soup or mixed salad. You can also use the cooking water for soups or sauces, for example. It contains about 50 percent of the valuable mustard oils that dissolve from the kohlrabi during cooking.
Unlike most other types of cabbage, kohlrabi is easy to digest and has a particularly high nutrient content. In order to ensure the healthful integrity of the vegetable, make sure to keep cook times short when preparing kohlrabi. Steam it in a little salted water or broth for a maximum of 10-15 minutes, taking it out when it is still relatively firm. Whole roots need a while longer to cook, about 20-30 minutes. Those who like the fine cabbage taste of kohlrabi are spoilt for choice. The crunchy texture makes it delicious raw when tossed into salads. It’s also delicious in casseroles, gratins or vegetarian buffers.
