How to Roast a Rack of Lamb？

Is there anything more luxurious than a rack of lamb? When you see the movies and TV shows of yesteryear what is the one cut that is shown to signify luxury? That would be a beautiful, and perfectly cooked, rack of lamb. Lamb is consumed the world over yet we here in America reserve it to special holidays such as Christmas, Passover, and Easter. Some people believe it has a “gamy” flavor, they do not know how to prepare it, or it’s just too intimidating. However, with proper temperature control and some basic techniques, we can ensure the most perfectly cooked rack of lamb every time.

HOW TO CLEAN A RACK OF LAMB

A rack of lamb can be very intimidating. There is a large eye of meat at the end of a series of very thin bones that are covered with a dense fat cap. This hard lamb fat is where some of the most intense, and to some, “gamy” flavors come from. Start by loosening up the fat against the eye of the meat with your fingers and slowly peal this back towards the bones. Use a sharp boning knife to separate any areas where the membrane is holding on tightly. Next lay your knife flat against the bones and, using small slashes, work your way from one end of the bones to the other. On a rack of American lamb, you do not want to remove as much of the fat cap as we are here because there is a section of meat that runs through the fat cap just above the eye. For American lamb remove most of the fat cap from the eye of the meat, leaving a small triangle of fat above. Next flip the rack over and use the tip of your knife and fingers to remove the membrane from the back of the rack. This membrane does not break down while cooking and can be tough to chew. When you have the membrane removed its time to clean the bones.

HOW TO CLEAN THE BONES

This process takes time and is optional but with a few extra minutes you can make your rack of lamb look restaurant ready! Start by cutting from the top of the bone down to the top of your fat cap or the eye of the meat (careful not to cut into the meat as you can unseat the bone). Make a U-turn and cut up the side of the next bone over. Repeat this process across the entire rack. Flip the rack over so you are seeing the backside of the bones. Lay the blade of a small knife at the base of the bone, perpendicular to the bone, and scrape to the tip. You are releasing the membrane from the back of the bone making the next steps much easier. Once you have removed the membrane from the back repeat the same techniques but on all sides of each of the bones. Once you have all the bones scraped, use a towel scrub any remaining membrane off the bones. This process is called Frenching and when you are done you will have perfectly clean bones that will stay clean during roasting. The rib scraps can be saved to be added to a braised lamb ragu or even a meaty sauce down the line.

SEARING, COATING, ROASTING

Liberally season the lamb with kosher salt and cracked black pepper. Add vegetable oil to your skillet and bring to just smoking. Add the rack, meat side down, and sear for 1.5-2 minutes or till nicely seared. Flip and sear the bottom of the rack for another 1.5- 2 minutes. Repeat with the bone side, this step is important and will create even more flavor in your final dish. Remove the meat from the pan and let cool on a plate. While the meat is cooling make your crust with the chopped pistachios, breadcrumbs, minced garlic, chopped rosemary, olive oil and melted butter. Season with salt and cracked black pepper then mix till the mixture clumps together. Take this time to preheat your oven to 400°F (204°C). Rub Dijon mustard on all sides of the meat then add the coating, using your hands to pack a thin layer onto the meat. Insert a probe from the Chefstemp Quad XPro into the center of the meat and set your high alarm for 120°F (49°C). Roast the lamb till this temperature is reached, doing a final check with the FinalTouch X10 probe thermometer, and remove to a plate to rest for 8 minutes before slicing. It is important to pull the rack at the correct temperature with the knowledge that the meat will continue to cook up to as many as 15°F after being removed from the oven.
