Easter Special Dinner recipe - Roasted Spiced Lamb

Ingredients
1 Leg of Lamb, about 6 pounds
2 1/2 tsp Salt
1/4 tsp Pepper
2 tsp Cinnamon
2 tbsp All-Purpose Flour
1 small Bay Leaf
1 tbsp Dried Onion, minced
Method
Wipe lamb with a damp cloth. Do not remove fell. Combine salt, pepper and cinnamon; rub all over leg of lamb. Insert a meat thermometer into the fleshy part of the leg of lamb, to check the temperature. By doing so, make sure that you do not insert the thermometer in the bone of the lamb.
Place the lamb on a rack in a shallow roasting pan and roast for about 3 to 3 1/2 hours, or until the thermometer reads 160° to 165° for medium, 175° for well done.
Remove lamb to a heated platter and keep warm, while making the sauce.
Pour off cooking juices, reserving two tablespoons in the roasting pan. Stir flour into roasting pan juices. Gradually stir in two cups of cold water
Add bay leaf and minced onion to the mixture. Reduce heat and cook the mixture over simmer, for five more minutes.
After the sauce is made, serve it with the lamb.
