Christmas ham, almost holy? I have refined my technique over the years. Optimal temperature of the ham should be 72-75 Celsius. But the important thing to keep in mind (as with all meat) is that it goes on reheating when you take the meat out of the oven. My ham is at 67 degrees, wrap it in foil and it will end up at around 71-72 degrees after 10 minutes. First I will remove the fat/skin and then I will grill it with a super yummy mustard mixture! #Food
