cut 1" slits all over the sucker, stick thin slivers of garlic and a small sprig of rosemary in each slit, rub with olive oil, sprinkle with sea salt and frezhly grpund black pepper.
place on a rack in a deep baking dish over halved, large, new potatoes and halved onions (that both have been tossed in olive oil, paprika, turmeric, thyme, and s&p), and put in a 350 degree oven until the meat reaches about 145 degrees in the thickest, meatiest part away from a bone.
about half way through, you should scoop and turn the potatoes and onions so they crisp on more than one side.
man, i want some lamb and spuds right now.
