This is the famous 'baba ganoush' from Egypt. It's called 'moutabal' in the Lebanon. Roasting the brinjal gives it a mellow flavour.
I just made this and it is absolutely awful. The lemon juice curdled the greek yoghurt. I have looked up other recipes for Baba Ganoush on line and they are nothing like this one... ie they don't have yoghurt in them! What a waste of fairly expensive ingredients :-( - 28 Jun 2012 (Review from Allrecipes UK | Ireland)
