Hi, I have ordered an 8kg gammon ham on the bone. I need to buy a pan to boil it in before roasting. Can anyone help me out on what size I should buy? Or maybe a big deep tray would be better and just cover and turn it every so often? I guess I need to know some rough dimensions of the thing, butchers weren't that helpful holding up their hands to give me an estimate.Any good recipes?
