What is it? Kabu

Wondering what that strange purple vegetable is in your CSA? Here's a blurb:

Kabu (turnip)Kabu has been widely grown and consumed in Japan since the 7th century. There are many different varieties with different shapes, sizes and colors, and it's commonly eaten raw, marinated or pickled. The most common variety is much more delicate than the turnips you usually think of: beautifully smooth, white and round, a little larger than the size of golf balls. The light green leaves have jagged edges and can also be pickled or chopped up and enjoyed in salads or cooked in miso soup. The flavor is somewhat similar to daikon, but milder and the texture, softer. The roots are high in vitamin C and iron; the leaves are high in fiber, vitamin A, and calcium.

Per Mamma Licia, Kabu tastes great grilled on the barbecue.
