No this is not an Israeli version of San Francisco sourdough. It is a simple sourdough loaf using jerusalem artichokes from my garden. I am sure that you could use this basic recipe for almost anny root vegetable, though the water would need to be adjusted depending on the moistness of the vegetable.
The technique is the same as all of my loaves, so I won't repeat it.
Peel 300g of Jerusalems (yielded 175g of mashed vegetable once peeled and cooked.) Put immediately into a pot of water with a slice of lemon in it. Boil for maybe 10-15 mins (until soft). Put through mouli (take the bit of lemon out first), or mash.

I don't know (yet) whether this loaf will have the same potent side effect as the soup that I made on the weekend. But perhaps don't consume large amounts before going to the opera.
Surprisingly strong flavour of Jerusalem artichoke came through in the bread, enhancing/balancing the sourness of the loaf. Crumb a little denser than I would have liked.
