Place pineapple juice in slow cooker
mix in a bowl remaining ingredients
Cover ham with brown sugar mix and put in slow cooker
cook on low for approx. 5hrs
PLEASE NOTE Ham is already cooked, so its just in there to get the flavour into it, if you need it sooner its fine to take it out
Strain left over liquid into a saucepan, add cornflour to thicken.
Drizzle over ham before serving
The sauce is very sweet, so I wouldn't recommend using it too liberally :)
