Preheat oven to 325°F (165°C). Place the ham cut-side down in a roasting pan. Cover loosely with foil.
In a saucepan, combine brown sugar, honey, mustard, butter, cloves, and juice (if using). Heat gently until smooth.
Bake the ham covered for about 1 hour and 15 minutes, until warmed through.
Remove foil and brush generously with glaze.
Return to the oven uncovered and bake 30 minutes more, glazing every 10 minutes, until caramelized.
Remove from oven and let rest for 15 minutes before slicing. Serve with extra glaze
