I've slow cooked my ham. Can I glaze it now?

[whatagradeA]

I did my ham in the slow cooker and it's very nice and all, but it's huge and we're bored already! Now that it's cold can I glaze it? I'm guessing I would need to fully heat it through again, as with reheating meat generally? So what do I do and how?!

I've gathered I need to cut the skin off and score the fat that's left. What would you put on it? Honey maybe? And how long and what temp to cook it at?

Thanks!

We did a glaze made of mustard/marmalade/brown sugar and a bit of water.
Cooked in fairly high oven for about 25 mins. Keep a close eye on it though, sugar etc burns very quick.

Thanks. I'll give it a try
