Remove heat from packaging, discarding the glaze, and place face down in a roasting pan (you'll want to use one that's at least 1" deep because there'll be accumulating juices).
Cover pan with foil and bake for 1 1/2 hours or until internal temperature reaches 135 F.
Combine remaining ingredients in a saucepan and bring to a simmer.
Brush glaze over the ham and let cook another 5 minutes.
Remove ham from oven and let rest at least 15 minutes before slicing.
Serve remaining warm glaze on the side for drizzling of the sliced ham.
