If you read far enough into this article, you see that my cousin Boaz has been quoted. He'd offered to take me on a tour of the shuk to search for these culinary oddities but it never happened (all my fault). And the picture that he sent me (think of a regular cucumber, a little lighter green and hairy) is a huge file and I can't upload it, so you'll have to use your imagination.
The stranger thing about all of this is that a friend sent me the article just because she thought I'd find it interesting. Not knowing Boaz (or that he was quoted), or having any idea that I would know what this strange vegetable is.
