Need help with my ham!
I've got a bone-in spiral sliced Cook's Ham and it says 275 degrees and 10 minutes for every pound--so mine will take about 3 hours to heat to 140 degrees.
I just put mine in a roasting pan and cover tightly with foil. Heat for 2 1/2 hours, remove, and smear my glaze on. Leave the foil off for the last 30-40 minutes of cooking.
The center of the ham should be 140 at serving
