Linda's lovely leg of lamb recipe

This is one of those recipes that always has the "wow" factor, and many requests have been made for the recipe, so I am sure Linda will not mind me sharing it:

Mix:
1 cup tomato sauce
1 cup of preferably Mrs Balls Chutney
1/4 cup worcester sauce
1/2 cup hot water

Insert slithers of garlic all over into a leg of lamb.
Rub mustard powder all over the lamb.
Place in a roasting dish.
Add 500ml litchi juice(if you can't find litchi then use apple, but litchi definitely makes the sauce a lot nicer)
sprinkle with olive oil.
Pour sauce over the lamb and cook for 2 hours at 180 deg. Spoon sauce over lamb every half hour. Slice lamb and put back in the oven in the sauce and allow to brown(see bottom photo below)..
