Glazed Spiral-Sliced Ham

Ingredients

1 (7- to 10-pound) spiral-sliced bone-in half ham
1 large plastic oven bag
1 recipe glaze (recipes follow)

Leaving ham’s inner plastic or foil covering intact, place ham in large container and cover with hot tap water; set aside for 45 minutes. Drain and cover again with hot tap water; set aside for another 45 minutes.
Adjust oven rack to lowest position and heat oven to 250 degrees. Unwrap ham; remove and discard plastic disk covering bone. Place ham in oven bag. Gather top of bag tightly so bag fits snugly around ham, tie bag, and trim excess plastic. Set ham cut side down in large roasting pan and cut 4 slits in top of bag with paring knife.
Bake ham until center registers 100 degrees, 1 to 1-1⁄2 hours (about 10 minutes per pound).
Remove ham from oven and increase oven temperature to 350 degrees. Cut open oven bag and roll back sides to expose ham. Brush ham with one-third of glaze and return to oven until glaze becomes sticky, about 10 minutes (if glaze is too thick to brush, return to heat to loosen).
Remove ham from oven, transfer to carving board, and brush entire ham with one-third of glaze. Let ham rest, tented loosely with aluminum foil, for 15 minutes. While ham rests, heat remaining one-third of glaze with 4 to 6 tablespoons of ham juices until it forms thick but fluid sauce. Carve and serve ham, passing sauce at table.
