Kohlrabi (from the German for turnip cabbage; Brassica oleracea Gongylodes Group), also called German turnip, is a biennial vegetable, a low, stout cultivar of wild cabbage. It is the same species as cabbage, broccoli, cauliflower, kale, Brussels sprouts, collard greens, savoy, and gai lan.
The name comes from the German Kohl ("cabbage") plus Rübe ~ Rabi (Swiss German variant) ("turnip"), because the swollen stem resembles the latter. Kohlrabi is a commonly eaten vegetable in German-speaking countries and American states with large ancestral German populations such as Wisconsin, but is also very popular in the northern part of Vietnam where it is called su hào, and in eastern parts of India (West Bengal) and Bangladesh where it is called 'Ol Kopi'. It is also found in the Kashmir valley in Northern India and is there known as 'Monj-hakh', 'monj' being the round part, and 'hakh' being the leafy part. This vegetable is called 'Nol Khol' in Northern India, 'Navalkol' in Maharashtra, 'Navilu Kosu' in Karnataka and in Ceylon as 'Nol col' (the Turnip Cabbage). It is also native in Cyprus where it is known as 'kouloumpra' ("κουλούμπρα").
Kohlrabi has been created by artificial selection for lateral meristem growth (a swollen, nearly spherical shape); its origin in nature is the same as that of cabbage, broccoli, cauliflower, kale, collard greens, and Brussels sprouts: they are all bred from, and are the same species as, the wild cabbage plant (Brassica oleracea).
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.
Except for the Gigante cultivar, spring-grown kohlrabi much over 5 cm in size tend to be woody, as do full-grown kohlrabi much over perhaps 10 cm in size; the Gigante cultivar can achieve great size while remaining of good eating quality. The plant matures in 55–60 days after sowing and has good standing ability for up to 30 days after maturity. The approximate weight is 150 g.
There are several varieties commonly available, including 'White Vienna', 'Purple Vienna', 'Grand Duke', 'Gigante' (also known as "Superschmelz"), 'Purple Danube', and 'White Danube'. Coloration of the purple types is superficial: the edible parts are all pale yellow. The leafy greens can also be eaten. One commonly used variety grows without a swollen stem, having just leaves and a very thin stem, and is called Haakh. Haakh and Monj are popular Kashmiri dishes made using this vegetable. In the second year, the plant will bloom and develop seeds. Kohlrabi also comes in three different colors: white, purple, and pale green.
Preparation and use
Kohlrabi stems (the enlarged vegetal part) are surrounded by two distinct fibrous layers that do not soften appreciably when cooked. These layers are generally peeled away prior to cooking or serving raw, with the result that the stems often provide a smaller amount of food than one might assume from their intact appearance.
The bulbous kohlrabi stem is frequently used raw in salad or slaws. It has a texture similar to that of a broccoli stem, but with a flavor that is sweeter and less vegetal.
Kohlrabi is an important part of the Kashmiri cuisine and one of the most commonly cooked foods. It is prepared with its leaves and served with a light soup and eaten with rice.
In Cyprus it is popularly sprinkled with salt and lemon and served as an appetizer.
