I'd do the same as funny.....make small slits all over and put slithers of garlic in with a small sprig of rosemary. It also depends how you like it cooked. I like it pink.
Cook it slowly, covered in foil on a bed of garlic cloves (no need to peel them) and sprigs of Rosemary. Be sure to let it rest for a few minutes before carving so that the juices are sucked back into the meat.
Definitely my favourite roast meat although I think shoulder of lamb is even more tasty.
In addition to the garlic slivers and/or rosemary in the slits, I add anchovies................the gravy made with those juices is fan-bl00dy-tastic............
