ham - what do i need to know?

[sloane]

okay, anxiety is a bit melodramatic but i am feeling slightly nervous about buying the ham for our christmas lunch this year (we're going to DP's mum for lunch & she's getting the turkey so i said we'd buy the ham). i'd like to do a baked ham just cos i've always wanted to but i have never, ever bought the ham for christmas before.

are the ones in the supermarket okay? is there a better place to get one? i think i'll need one that is around 6-7kg.

anyone have any suggestions? i think i'm going to do a cranberry sort of glaze...never had baked ham before either - do you serve it hot/warm? or can it be cold? ()
