I made a half recipe of this for our dinner using 4 very large yellow potatoes. It was good, but I wish I had made a full recipe of the sauce as it was a bit on the dry side. I added some garlic into the meat mixture and a bit more than half of the baharat. I really wanted to throw some fresh parsley into the meat mix too, but controlled myself and just sprinkled a little over to finish. In our opinion, the yoghurt was absolutely necessary as it added a bit more moistness to the dish. The recipe was a little hard to follow with ingredients not listed in the order used in the instructions. I would definately make this again though using more sauce and the other couple of small modifications. I suspect I made these "wrong" not hollowing them out the right way, but I did my best with a knife and a spoon and the flavour was still great.
