Cut the lamb into 6 chops, or better yet have your butcher
do it for you. Trim the chops removing excess fat and
skin. Slice the Lamb Kidneys.
Peel and slice the potatoes
Grease a large casserole and place a layer
of potatoes in the bottom. Arrange the chops on top and
season with the Salt, Pepper, Nutmeg and Mace. Layer the
sliced kidneys and onions on top of the chops, top with
the oysters if using and finish up with a top layer of
potato.
Brush the top of the potatoes with melted
butter and cover with a sheet of greaseproof paper. Place
in the oven for about 1 1/4 hours.
At this point remove the paper and continue cooking for
anoth 30-45 minutes until the top is a nice crisp golden
brown.
