Raw, cooked, diced, fried, stewed, julienned, fresh from the garden, or stored for winter, this inter-planetary looking cole crop should be a more familiar sight in American gardens (not just in Roswell). This variety has a lovely purple hued skin and light green interior, giving it the luminescence of a flying saucer.
No, Kohlrabi does not actually come from outer space. It comes from Europe, as do most members of the cabbage family. Rarely tasted by most Americans, its popularity has been quite steady on the other side of the pond since the 15th Century. And, it's easy to see why: the flesh is crisp and refreshing and redolent of sweet cabbage, and when chopped and roasted it softens, like an apple, with a flavor and texture that is out of this world. Seeing (and tasting) is believing.
