This is an easy - cook it in an hour - recipe for a boneless butterflied leg of lamb. This recipe can be adapted for bone-in leg of lamb - just adjust for the size of the piece of meat. For a different taste, replace curry powder with 1 tbs dijon mustard. Different effect, but same base. I developed this recipe while just playing around in the kitchen one day - wanting to give my lamb a subtle kick without taking it over the top. This has become an absolute family favorite.
