The recipe is Tunisian by way of a small bakery's cookbook. I can PM you the recipe if you'd like. It's very simple and quick to make, so just grab some quality ingredients and you should be good! Not quite the same as the Afghan dessert you mentioned, but it is refreshingly different (and a good pairing with coffee and mint tea).
On the topic of Middle Eastern/South Asian desserts: I will say that my true specialty is baklava. I've played with a couple of different styles over the years (ie. Greek, Turkish, Persian) and have always been pleased with the results. It's something I only make for a crowd, though.
