ROAST LAMB OVEN TEMPERATURE RECIPES

Steps:

• Heat oven to 425 degrees. Use a small sharp knife to make about a dozen incisions, each about 2 inches deep, through the fat that covers the top of the meat. Using a mortar and pestle or a blender, blend 2/3 of the anchovies (or 2/3 of the mustard if using), the rosemary leaves and the garlic cloves into a chunky paste. Using your fingers, press paste deeply into incisions.
• Mix remaining anchovies (or mustard) and the butter into a paste. Smear this mixture all over the surface of the roast. Season liberally with black pepper. (Do not add salt; the anchovies are salty enough, and so is the mustard.) Place the lamb on a rack in a roasting pan, fat side up, and squeeze the lemon halves over. Pour the wine around the roast into the pan.
• Roast 15 minutes, then reduce heat to 350 degrees and roast until internal temperature reaches 130 to 135 degrees (for medium-rare or medium meat), about another 60 to 90 minutes. Baste every 20 minutes or so with the wine and drippings in the pan, adding more wine as needed to keep the liquid from scorching. If possible, for the last 15 minutes of cooking, use convection or a broiler to crisp the fat on the roast.
• Remove pan from the oven, remove rack from the pan, and let the roast rest on the rack for at least 15 to 20 minutes in a warm place, tented with foil. The internal temperature will rise to about 140 to 145 degrees.
• To make sauce from the pan drippings, remove a few tablespoons of fat by tipping the pan and spooning off the top layer. Put the pan over medium heat until the liquid simmers. Taste the simmering liquid and whisk in more wine, 1/4 cup at a time, until the consistency and flavor are right. Do not let the mixture become syrupy; it should be a sharp jus, not a thick gravy.
• Carve lamb into 1/2-inch-thick slices and arrange on a heated platter, decorated with rosemary sprigs. Serve with piping hot gravy.

Steps:

• Heat oven to 240C/fan 220C/gas 9. Pound the garlic, half the oregano, lemon zest and a pinch of salt in a pestle and mortar, then add the lemon juice and a drizzle of olive oil. Stab the lamb all over with a sharp knife, then push as much of the herb paste as you can into the holes.
• Tip the potatoes into a large roasting tin, then toss in the remaining olive oil and any remaining herb paste. Nestle the lamb amongst the potatoes, roast for 20 mins, then reduce the temperature to 180C/fan 160C/gas 4. Roast for 1 hr 15 mins for medium-rare, adding another 15 mins if you prefer your lamb medium. Baste the lamb once or twice with the juices and toss the potatoes. When the lamb is done to your liking, remove from the tin and let it rest. Throw the rest of the oregano in with the potatoes, scoop from the tin and keep warm.
• Place the roasting tin over a medium flame, add the canned tomatoes and olives to the pan juices, then simmer for a few mins. Serve the lamb with the potatoes and sauce and a simple salad.
