Irish ham may be ordered online from foodireland.com. If using an 8 1/2-pound spiral-sliced bone-in ham, proceed with step 1 as directed. Tent ham in skillet with aluminum foil; roast at 350°F until the internal temperature registers 110°F, 1 hour and 30 minutes to 2 hours, turning and basting ham every 30 minutes. Remove foil, and place ham on its side in skillet. Proceed with recipe as directed in Steps 3 through 5 (the spiral ham will not be tied, so there is no need to untie it in Step 5).
