Make several small slits about 1-2cm deep into the lamb and insert a half a garlic clove and some rosemary sprigs in each hole
Place lamb in slow cooker bowl
Mix stock powder with water, combine mint sauce with this liquid and pour into base of slow cooker bowl
Cook on low for 6-8hrs depending on your machine
I spooned the juices from the bowl over my lamb several times over the course of the day to achieve this color but that's optional.
Remove garlic/rosemary from meat prior to carving
Beautiful served with roast vegetables and gravy made on the pan juices
You may also chose to place your roast vegetables under the lamb when you put this dish on if you prefer :)
