Archer Farms honey glazed spiral ham, like other brands, is sold precooked and pre-sliced in a helical form (ham peels off in a spiral). Spiral ham is great for cold plates and sandwiches, and can be eaten right out of the package. It can nevertheless be cooked further, or technically, reheated, instead of being consumed cold. Depending on personal preferences, cooking tools and the ham itself, the length of time it takes to reheat spiral ham can vary.
The heating time of an entire spiral ham depends on the size and weight. In an oven preheated to at least 135 degrees C, spiral hams should be baked at a rate of about 10 to 15 minutes per pound. Therefore, a quarter-sized ham will take 1 to 1 1/2 hours, while a half-sized ham will take about 2 hours. A whole ham will then take 3 to 3 1/2 hours.
Check the Archer Farms package for a USDA label. This indicates that the specific ham came from a processing plant under inspection by the United States Department of Agriculture and therefore requires a heating temperature of 60 degrees Celsius and a heating time of 10 minutes per pound. Not all Archer Farms hams come from the same plant, so check for the label.
Archer Farms Spiral Hams already come with their own honey glaze, but reheating them can cause the glaze to dry out and lose flavour. To reglaze a spiral ham, brush a new glaze all over and keep in the oven (preheated to 275 degrees) for about 10 minutes. You can also heat up glaze in a microwave oven for about 40 seconds and then serve with the ham.
The entire spiral sliced ham does not need to be heated if only a few slices of it are going to be used. Start with no more than a minute in a microwave oven, test, then put in for longer if needed. If using a toaster oven (large conventional cooking ovens are not necessary), set on bake and keep in for about five minutes. Depending on the amount of ham and appliance quality, the time may be longer or slightly shorter.
