Kohlrabi, also known as German Turnip, is a vegetable that belongs to the family of wild cabbage (Brassica oleracea) that has gained popularity in the recent decade for its innumerable health benefits. Kohlrabi is in fact another cultivator of the same species from which cabbage, broccoli, cauliflower, kale, Brussels sprouts etc are bred from.

Italian botanist Mattioli first recorded its presence in 1554 that it had ‘come lately into Italy’, and ever since it has been in wide cultivation across Austria, Germany, England, Spain and parts of East Mediterranean region.
