About
Kohlrabi (German: [koːlˈʁaːbi] ; pronounced in English; scientific name Brassica oleracea Gongylodes Group), also called German turnip or turnip cabbage, is a biennial vegetable, a low, stout cultivar of wild cabbage. It is a cultivar of the same species as cabbage, broccoli, cauliflower, kale, Brussels sprouts, collard greens, Savoy cabbage, and gai lan.
It can be eaten raw or cooked. Edible preparations are made with both the stem and the leaves. Despite its common names, it is not the same species as turnip or rutabaga, although both are in the genus Brassica.
Uses
Raw kohlrabi is 91% water, 6% carbohydrates, 2% protein, and contains negligible fat (table). In a 100 g (3.5 oz) reference amount, raw kohlrabi supplies 27 calories, and is a rich source (20% or more of the Daily Value, DV) of vitamin C (65% DV) and a moderate source (10–19% DV) of copper and potassium, with no other micronutrients in significant amounts (table).
