Method
1.Preheat oven to 160°C/140°C fan-forced. Place lamb in a large roasting pan. Using a small sharp knife, make 10 small incisions in top of lamb. Place a slice of garlic in each slit. Drizzle lamb with oil; sprinkle with oregano and season with salt and pepper. Pour juice, stock and wine into base of pan.
2.Cover pan tightly with a layer of baking paper then a layer of foil. Roast 2 hours. Add potato to pan; cook, covered, 1 hour and 45 minutes.
3.Remove paper and foil; cook a further 30 minutes or until lamb is very tender and potato is cooked. Transfer lamb to a large plate. Cover with foil; rest 10 minutes. Place potato in oven to keep warm.
4.Carve lamb and serve with potato. Drizzle with pan juices. Serve with lemon wedges
Omit wine – use extra stock. For best result, place oven shell so top of roasting pan is at centre of oven. Use white balsamic instead lemon juice.
