Preheat oven to 400F
Peel and soak the potatoes for 20 minutes.
Rub the lamb with the salt and pepper rub.
Toss the garlic wedges in salt & pepper.
Make deep slits all over the lamb, and push in the garlic wedges.
Rub the oregano all over the lamb, and then rub with the olive oil.
Set the lamb aside.
Drain and rinse the potatoes.
Cut into long, thick wedges, and place in a bowl.
Toss the potatoes in the Taters mix
Spread the potatoes in one layer in a pan large enough to fit the lamb.
Place the lamb, top side facing down.
Pour hot water in the corner of the pan so it covers the potatoes half way.
Cover with foil and place in the oven.
Roast for 20 minutes, remove foil, reduce heat to 340F, and flip the lamb over.
Roast until lamb turns brown, and internal temperature is reached. From here, it's typically 30 minutes + 30 minutes per pound over 3.
Once the lamb is done, remove it, cover, and continue roasting the potatoes until the water has all been absorbed, and only the oil is left in the pan.
Let everything rest 15 minutes before serving.
