With the bone attached, these bite-sized lamb chops are a great finger-food/appetizer for a small crowd. Also, they can be made a day ahead, refrigerated, then served at room temperature. The gremolata topping adds some nice color and brightness but should be prepared on same day of your event. If you would like to prepare your own Ras el hanout, there are many blends, including my own, here on Food.com. If you are using a blend commercially prepared, the only one I can recommend is from Williams/Sonoma. I have tried another one that is popular and available in markets and online, but the Williams/Sonama blend is far better, JMHO. If you purchase preserved lemon, they are quite spendy. It is easy to make your own, but they need to be made a month ahead of time so they can ripen.
