I have tried several recipes for chicken with lemon & olives but it never did taste the same as I had while in Morocco. When visiting my Moroccan sister-in-law this week she showed me how it is traditionally made. Many times it is served with fried potatoes on top. (Peel & cut the potatoes into french fry length then fry until golden brown.) Smen is rancid butter similar to ghee but with spices added. It can be purchased online or at a Middle Eastern store. Prep time does not include marinating time.
