Chocolate Babka (Sourdough, Parve?)
I just finished writing up the recipe on my blog.
You can find it here http://foolishpoolishbakes.wordpress.com/2008/12/18/chocolate-babka-sourdough/ 
I'm not sure if the recipe qualifies as Parve. If there's anybody who can give me a definitive answer, I'd be most appreciative.
