Notes
A leg of lamb is really forgiving when it comes to cooking time. Every oven will vary, so if you find the meat isn't quite tender enough, the you can put it back in the oven and it will still be nice and juicy even if it is cooked for 45 minutes to an hour longer.
The nutritional information for this will not be totally accurate, because there is a lot of fat the comes out when cooking, which is not used.
You don't even need to carve this lamb. It should be so tender that you should be able to pull the meat off the bone with two forks.
