Kohlrabi (German turnip)

Kohlrabi (German turnip or turnip cabbage) (Brassica oleracea Gongylodes group) is an annual vegetable, and is a low, stout cultivar of cabbage. Kohlrabi can be eaten raw as well as cooked.

I bought this to try it out. Sadly, I didn't like it, the skin was very thick and tough.
