Kohlrabi (Kohl Rabi)
Feb 27th, 2011, by Alex Zorach
These kohlrabi were for sale at the Newark, Delaware farmer's market for 99 cents a pound. Kohlrabi is a form of cabbage; the growth is actually a swollen part of the stem, not a root, and not a leaf, making it somewhat distinct from both root vegetables and heads of cabbage.
I have never to my knowledge eaten this vegetable, and I have certainly never bought it, but it is one I would be curious about.
